Question

How many moles of gas are needed to fill a 2000 ml container at 77 ° F and a pressure of 1.0104 Bar.

Answer 1

Answer:-

Given:

Volume of gas (V) = 2000 ml = 2 L

Pressure (P) = 1.0104 bar.

Temperature (T) =( 77° + 459.67)*5/9 = 298.15° K

Gas Constant (R) = 8.31 L*bar/K*mol.

Let ,

number of moles = n.

By using Ideal Gas Equation,

→ PV = nRT

→ (1.0104)(2) = n(8.31)(298.15)

→ n = 2.0208/2477.6

→ n = 0.0008 mol.
