It depends on whether the element is a gas or a liquid.
It looks as if you are trying to use the molar mass to convert grams or moles of an element to litres of the element.
1. If the element is a gas
You convert grams to moles and then use the Ideal Gas Law to find the volume.
Example 1: What is the volume of 10.0 g of chlorine gas at 1.00 atm and 25°C?
Moles of chlorine = 10.0 g Cl₂ ×
The Ideal Gas Law is
Example 2: What is the volume of 0.150 mol of chlorine gas if its density is 2.90 g/L at 1.00 atm and 25°C?
Here you can convert moles to grams, and then use the density to find the volume.
0.150 mol Cl₂ ×
10.64 g Cl₂ ×
2. If the element is a liquid
Example 3. What is the volume of 6.25 mol of bromine? The density is 3.12 g/mL.
6.25 mol Br₂ ×
