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.
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
