Question

If 0.274 moles of a substance weighs 62.5 g, what is the molar mass of the substance, in units of g/mol?

Answer 1

Here’s a trick :
The unit is g/mol
And you imagine “/” as a division.
So gram is divided by the number of moles
Therefore, the molar mass = 62.5g/0.274mol = 228.1 g/mol (correct to one decimal place)

Answer 2

The molar mass of the substance will be "228 g/mol".

Given values are:

• Mass of substance = 62.5 g
• Number of moles of substance = 0.274 moles

Now,

The Molar mass of the substance will be:

= $\frac{Grams}{Moles}$

By substituting the values, we get

= $\frac{62.5}{0.274}$

= $228 \ g/mol$
