Answer to Question #261368 in Chemistry for Base

Question

2.0 moles of an idea has are at temperature of -133 degrees Celsius and a pressure of 2atm .what volume in dm3 will the gas occupy at that temperature? R = 0,082 atm, dm3 K -1mol-1

Answer 1

P = 2 atm

V = unknown

n = 2.0 mol

R = 0.082 atm dm³ K^-1 mol^-1

T = -133°C = 140 К

Solution:

The Ideal Gas equation can be used: PV = nRT

To find the volume of gas, solve the equation for V:

V = nRT / P

V = (2.0 mol × 0.082 atm dm³ K^-1 mol^-1 × 140 К) / (2 atm) = 11.48 dm³

V = 11.48 dm³

Answer: 11.48 dm³
