Question

354.4 g of chlorine gas (MW=70.9g/mol) is held in a vessel with a fixed volume of 70.0 L. What is the pressure of the gas in atmospheres if its temperature is 30.0 Celsius?

Answer 1

Explanation:P = 1.73atm

mole(n) = mass in grams/ molecular weight

n = 354.4/ 70.9

n=4.8717mol

From PV =nRT

P=nRT/V

P= 4.8717×0.0821×303/70

P=1.73atm

Answer 2

Answer: 1.78
