Question

Calculate the volume occupied by 10 moles of hydrogen gas at 145K and 705 Torr.

Answer 1

The volume occupied by 10 moles of hydrogen gas at 145K and 705 Torr is 128.01L.

How to calculate volume?

The volume of a gas can be calculated using ideal gas law equation as follows:

PV = nRT

Where;

• P = pressure
• V = volume
• n = number of moles
• R = gas law constant
• T = temperature

• P = 705torr = 0.93atm
• V = ?
• T = 145K
• n = 10
• R = 0.0821 Latm/molK

0.93 × V = 10 × 0.0821 × 145

0.93V = 119.05

V = 128.01L

Therefore, the volume occupied by 10 moles of hydrogen gas at 145K and 705 Torr is 128.01L.
