Question

A container holds 35.8 moles of gas under 10.0 atm of pressure at 70.0 C. What is the volume of the container?

Answer 1

The correct answer is 101 L.

Answer 2

THE ANSWER

for solving this, we just use the formula of the equation of state

PV = n RT
where
P: pressure =10atm
V volume
n number of mole = 35.8 moles
R universal gas constant = 0.082
T: The temperature= 70°C= 343.15 Kelvin

therefore, for finding V
we have

V= (n RT) / P = 35.8 x 0.082 x 343.15 / 10 = 100.7 ≈ 101 L

the answer is V = 101L
