# What does mm stand for in chemistry?

millimolar (not comparable) (abbreviated as: mM) (chemistry, of a solution) Having a concentration of one thousandth of a mole per litre.

## What does mm mean in units?

A millimeter (abbreviated as mm and sometimes spelled as millimetre) is a small unit of displacement (length/distance) in the metric system.

## What unit is mm chemistry?

A millimolar (mM) is the decimal fraction of a molar, which is the common non-SI unit of molar concentration. For example, a 2-molar (2 M) solution contains 2 moles of a certain substance in one liter of a liquid or gaseous mixture.

## What does MN stand for in biology?

Manganese is a chemical element with the symbol Mn and atomic number 25.

## Does mm mean molar mass?

Molar mass (MM) is the mass of one mole of a substance. Molar mass is expressed in g/mol (grams per mole).

## What called mm?

millimetre (mm), also spelled millimeter, unit of length equal to 0.001 metre in the metric system and the equivalent of 0.03937 inch.

## What does mm mean in dilutions?

M= n/v = moles of solute / litres of solution. The units are moles per litre. The simplified version for the equation M=n/v is M=g/mm x L, g meaning grams, mm meaning the molar mass of the solution, and L meaning litres.

## Is mM the same as molarity?

The formula to convert Millimolar to Molar[M] is 1 Millimolar = 0.001 Molar[M]. Millimolar is 1000 times Smaller than Molar[M].

## How do you calculate concentration in mM?

Calculate concentration in millimolars using the formula: Molarity (millimolars)= Amount (in millimoles)/Volume of solution (in liters). In our example, the volume of the solution is 500 ml or 0.5 liters. The molarity of NaOH would be: Molarity (NaOH)= 12.5 millimoles/0.5 liters=25 millimolars.

## How many mM are in M concentration?

M↔mM 1 M = 1000 mM.

## What is medical term MN?

MN. membranous nephropathy. MND. motor neurone disease, also known as amyotrophic lateral sclerosis (ALS), Lou Gehrig’s disease or Charcot disease.

## What does MN mean in nursing?

MN – Master of Nursing.

## What does MN mean in healthcare?

MN. Medical Necessity. Necessity, Health, Medicare.

## What does mm mean in date?

DD/MM/YYYY. Two-digit day, separator, two-digit month, separator, four-digit year (example: 15/12/1999) MM/DD/YYYY. Two-digit month, separator, two-digit day, separator, four-digit year (example: 12/15/1999) YY/MMM/DD.

## What units are molarity?

In chemistry, the most commonly used unit for molarity is the number of moles per liter, having the unit symbol mol/L or mol⋅dm⁻³ in SI unit. A solution with a concentration of 1 mol/L is said to be 1 molar, commonly designated as 1 M.

## Is mole and molar mass the same?

One mole of a compound contains Avogadro’s number (6.022 x 1023) of molecules (molecular compound) or formula units (ionic compound). The molar mass of a compound tells you the mass of 1 mole of that substance. In other words, it tells you the number of grams per mole of a compound.

## How do you determine molarity?

As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the mass concentration or molar mass.

## What is mm suffix?

The Latin numeral M denotes thousands. Thus, MM is the same as writing “M multiplied by M,” which is equal to “1,000 times 1,000”, which equals 1,000,000 (one million).

## How do you make a mM solution?

A concentration of 70 mM is the same as 0.07 moles per liter. Take 0.07 moles/liter times 342.3 grams per mole and you have 23.96 grams needed per liter. To make 200 milliliters of your solution multiply grams/liter by liters needed. Since 200 milliliters is 0.2L, multiply 23.96 grams by 0.2L to get 4.792 grams needed.

## Is molarity the same as concentration?

Molarity is the most commonly used method of concentration. It is expressed as the number of moles of solute dissolved per litre of solution. Therefore, the unit of the molarity is mol/L. Molarity is also known as molar concentration and is represented by “M”.

## How do you make 10 mM solution from 1M?

Take 1 part of your stock solution and add 9 parts of solvent (usually water but sometimes alcohol or other organic solvent). In all cases you are diluting by the same factor. The concentration of the resulting solution is 1M /10 = 0.1M where 10 is the dilution factor.

## How do you convert mM to moles?

1 Millimolar [mM] = 0.001 Mole per liter [mol/l] – Measurement calculator that can be used to convert Millimolar to Mole per liter, among others.

## How many mM is a molar?

How many Millimolar make 1 Molar? 1 Molar [M] = 1 000 Millimolar [mM] – Measurement calculator that can be used to convert Molar to Millimolar, among others.

## Is mM same as M?

How many Millimeters in a Meter? Two of the most used metric system units are meters (m) and millimeters (mm). They both measure length, but differ in magnitude. According to the treaty signed by the International System of Units (SI) in 1959, 1,000 millimeters equal 1 meter.

## How do you make a 5 mM solution?

So: 5 ml of 1 M NaCl + 995 ml water= 1.0 liter of 5mM NaCl. Using this approach, you don’t have to worry about moles and such.
