Question
If 0.97 mol of a substance has a mass of 107.64 g, what is its molar mass?
Give your answer in g mol<sup>-1</sup> and to two decimal places.
Solution
The molar mass of a substance can be calculated using the formula:
Molar mass = mass of substance (in grams) / number of moles
Given: Mass of substance = 107.64 g Number of moles = 0.97 mol
Step 1: Substitute the given values into the formula:
Molar mass = 107.64 g / 0.97 mol
Step 2: Perform the division to find the molar mass:
Molar mass = 111.07 g/mol
So, the molar mass of the substance is 111.07 g/mol.
