    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
