# How do you use the molar volume gas at STP to determine the volume (in L) of a occupied by 33.6 g of neon at STP?

See below.

#### Explanation:

So neon occupies 33.6 g

First we find the number of moles of Ne= $\frac{m a s s}{\text{molar mass}}$
No. of moles= $\frac{33.6}{\text{20}}$
No. of moles= 1.68 mol

Then, we can find volume of the gas using:
No. of moles= $\frac{v o l u m e}{\text{molar volume}}$

where molar volume of the gas at stp= 22.4 $L m o {l}^{-} 1$

Make volume the subject of the formula

Volume= no. of moles x molar volume
Volume= 1.68 x 22.4

Volume of Ne= 37.6 L
