Problem

Calculate the volume occupied by 56.5 g of argon gas at STP. 

a) 22.4 L 

b) 31.7 L 

c) 34.6 L 

d) 1, 270 L 

e) 1, 380 L



Solution

We’re being asked to calculate the volume occupied by 56.5 g argon gas at standard temperature and pressure.


Recall that standard temperature and pressure (STP) is defined as 1 atm and 0 ˚C


For this problem, we need to do the following:

Step 1: Calculate the moles of Ar.

Step 2: Calculate the volume using the ideal gas law.
