# How do you find the molecular formula?

Divide the molar mass of the compound by the empirical formula molar mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.

## 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 the easiest way to learn chemical formulas?

Use the Periodic Table. To write chemical formulas, acquaint yourself with chemical symbols, most easily found on the periodic table of elements. The periodic table is a chart of all the known elements, and it often includes both the full name of each element and its symbol, such as H for hydrogen or Cl for chlorine.
