## How many moles are in 45 grams of water?

Solution : Number of moles of water `=(” Mass of water “)/(” Gram molecular mass of water “)= (45g)/(18g)= 2.5`.

## How many moles is NaCl?

One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.

## How many moles are in H2SO4?

This chemical is used as a chemical intermediate to manufacture other chemicals and cleaning metal surfaces. The formula for sulfuric acid is H2SO4. The molar mass of sulfuric acid is 98.07848 g mol.

## How many moles are in HCl?

Using periodic table you can find molar mass of HCl, which is 36.458 g/mol. This means 1 mol of HCl is 36.458 grams. So 20 g of HCl is 0.548 mol.

## How many moles are in NH3?

The moles of NH3 produced are 14 moles. First write the balanced chemical equation.

## How many moles of NaCl are in 3g of NaCl?

1 Answer. David G. 3 g is 0.075 mol of NaCl .

## How do you find the moles of OH in NaOH?

Every mole of NaOH will have one mole of OH-. Therefore [OH-] = 0.5 M. When the base neutralizes the acid, the number of moles of H+ = the number of moles of OH-.

## How do you convert to moles?

## How many atoms are in 4.5 moles?

A mole of anything has 6.022 x 1023 items in it. 4.5 moles of copper has (4.5)(6.022 x 1023) = 2.7 x 1024 atoms.

## How many moles are in CO2?

Mass of 1 mole (6.023 X 1023 molecules) of CO2 is about 44g.

## How many moles is O2?

Oxygen gas is O2 . O2 has a molar mass of 32g/mol . ∴ There are 1.25 moles of O2 in 40g of oxygen gas.

## What is the mole of oxygen?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.

## How many moles is a gram?

1 mole of a substance is gram molecular mass of that substance, which contains 6.022*10^23 constituent particles (i.e. molecules). 1 mole = 6.022*10^23 molecules.
