Question

calculate the molar mass of 1 mole of a pure substance weighting Xg

Answer 1

$1 \div$
1 by substance weight Xg

Answer 2

Answer: The molar mass of the substance is equal to X g/mol.

Explanation:

For calculating the molar mass of the substance, we will use the equation that is used to calculate the number of moles:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Given mass of the substance = X grams

Moles of the substance = 1 mole

Molar mass of the substance = ? g/mol

Putting values in above equation, we get:

$1mol=\frac{Xg}{\text{Molar mass}}\\\\\text{Molar mass of the substance}=Xg/mol$

Hence, the molar mass of the substance is equal to X g/mol.
