Calculate the pressure of 159.53 grams of chlorine gas at 53.5 degree celsius occupying a volume of 150 cm3

Question

????????

Answer 1

Convert grams to moles, remembering that chlorine is Cl2, and then use

PV = nRT

where n is the number of moles.

Over to you.  Good luck.

Answer 2

I agree with the person above.

PV=nRT

# moles Cl2: 159.53 g * 1mol/ 70.906 g = 2.25 mol Cl2

P(150 cm³) = (2.25 mol)(8.314472 cm^3·MPa·K-1·mol-1)(326.65K)

P = 40.74 MPa

convert the units as you wish.
