Question

How many moles of Xenon gas, Xe, would occupy 37.8L at STP?
Round to the nearest hundredth (2 decimal places)

Answer 1

Answer:

1.69 moles of Xenon gas will occupy a volume of 37.8l in STP conditions

Explanation:

We use the formula PV=nRT. The conditions STP are 1 atm of pressure and 273 K of temperature.

PV=nRT ----> n=PV/RT

n= 1 atm x 37, 8 L/ 0,082 l atm/K mol  x 273K

n=1,688555347 mol
