Question

A gas cylinder with a volume of 5.00 L contains 6.00 moles of oxygen gas

at a temperature of 90.0 K. What is the pressure inside the cylinder? The
Ideal gas law constant( R) is 0.0821 L atm/mol K*
8.87 torr
8.87 atm
0.0821 atm
0.0821 torr

Answer 1

8.87 atm

Step-by-step explanation:

From the question given above, the following data were obtained:

Volume (V) = 5 L

Number of mole (n) = 6 moles

Temperature (T) = 90 K

Gas constant (R) = 0.821 atm.L/Kmol

Pressure (P) =?

The pressure inside the container can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

P × 5 = 6 × 0.0821 × 90

P × 5 = 44.334

Divide both side by 5

P = 44.334 / 5

P = 8.87 atm

Therefore, the pressure inside the container is 8.87 atm
