Asked by admin @ 03/12/2021 in Chemistry viewed by 340 People

Use the van der Waals equation to calculate the pressure exerted by 1.475 molmol of Cl2Cl2 in a volume of 4.635 LL at a temperature of 299.0 KK .

Answered by admin @ 03/12/2021

Answer:

7.812atm

Explanation:

Using Van der Waals equation, which goes as follows:

Pv = nRT

Where;

P is the pressure

V is the volume (4.635L)

n is the number of moles (1.475mol)

T is the temperature (299K)

R is the universal gas constant (0.082057 L atm mol-1K-1)

Pv = nRT

P = nRT/V

P = 1.475 × 0.0821 × 299/4.635

P = 36.2081/4.635

P = 7.812atm
