Answer:

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 data: 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
