Question
A 0.201 -mol sample of an unknown gas contained in a $5.00 \mathrm{L}$ flask is found to have a density of $1.72 \mathrm{g} / \mathrm{L} .$ What is the molar mass of the unknown gas?
Step 1
We can do this by multiplying the volume of the gas by its density. The formula for this is: \[ \text{Mass} = \text{Volume} \times \text{Density} \] Show more…
