Question

The gram-formula mass of a compound is 74 grams. The mass of 1. 0 mole of this compound is.

Answer 1

The mass of 1.0 mole of this chemical compound is 74.0 grams.

Given the following data:

• Gram-formula mass = 74 grams per mole.

• Number of moles = 1.0 mole.

To calculate the mass of 1.0 mole of this chemical compound:

Note: The gram-formula mass is equal to molar mass.

How to calculate the mass of a compound.

Mathematically, the number of moles contained in a chemical compound is given by this formula:

$Number\;of\;moles = \frac{mass}{molar\;mass}$

Making mass the subject of formula, we have:

$Mass = number\;of\;moles \times molar\;mass$

Substituting the given parameters into the formula, we have;

$Mass = 1.0 \times 74$

Mass = 74.0 grams.
