Question

How many moles of gas are in a 34.2 L container at 1 atm of pressure and 123℉?

How many moles of gas are in a 22.4 L container at 1 atm of pressure and 89℃?


How many moles of gas are in a 16.7 L container at 1 atm of pressure and 273.15 K?

Answer 1

1.29 moles

0.753 moles

0.745 moles

Step-by-step explanation:

PV=nRT

n=PV/RT

n=(1)(34.2)/(0.0821)(323.7)

n=1.29

n=PV/RT

n=(1)(22.4)=(0.0821)(362.15)

n=0.753

n=PV/RT

n=(1)(16.7)/(0.0821)(273.15)

n=0.745

In the ideal gas equation, T is measured in Kelvin.
