A sample of chlorine gas fills a vessel at a temperature of 37oC. The vessel has a volume of 3L and experiences a pressure of 3atm. What is the mass of the chlorine gas in the vessel

25.1 g is the mass of chlorine in the sample

Explanation:

P. V = n. R. T

We apply the Ideal Gases Law to solve the excersise.

We need to convert the T°C to T°K → 37°C + 273 = 310K

We replace dа ta: 3 atm. 3L = n. 0.082 L. atm / mol. K. 310K

9 atm. L / (0.082 L. atm / mol. K. 310K) = n → 0.354 moles

We convert the moles to mass, to reach the answer

0.345 mol. 70.9g / 1mol = 25.1 g
