# Using the molar volume of a gas at STP , what is the volume (in L) occupied by 36.2 g of neon at STP?

Oct 18, 2016

The volume at STP is 40.7 L.

#### Explanation:

STP is defined as 1 bar and 0 °C.

The molar volume at STP is 22.71 L/mol.

$\text{Moles of Ne" = 36.2 color(red)(cancel(color(black)("g Ne"))) × "1 mol Ne"/(20.18 color(red)(cancel(color(black)("g Ne")))) = "1.794 mol Ne}$

∴ The volume of neon is

V = 1.794 color(red)(cancel(color(black)("mol Ne"))) × "22.71 L Ne"/(1 color(red)(cancel(color(black)("mol Ne")))) = "40.7 L Ne"
