# How do you calculate the formula of an element?

## How do you calculate the formula of an element?

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 find the volume of mercury?

By definition, ρ,density = Mass of stuffVolume of stuff . We want to find a volume, so: Volume = Massρ = 175⋅g 13.6⋅g ⋅mL−1 .

**How to calculate formula weight?**

formula weight, in chemistry, a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a formula by the number of atoms of that element present in the formula, and then adding all of these products together.

### How do you make formulas?

How do you name a formula? The first component in the formula is simply identified with the element name. The second component is named by taking the name of the element stem and adding the -ide suffix. The number of atoms in a molecule is determined using a scheme of numerical prefixes.
