Answer:

0.0345kg is the mass of 25L of the sample

Explanation:

Hydrophosphoric acid, H₃P = Phosphine has a density of 1.38g/L.

To solve this question we need to convert the volume of the gas to mass in grams as first and then to kilograms as follows:

Mass in grams:

25L * (1.38g / L) = 34.5g

Mass in kilograms:

34.5g * (1kg / 1000g) = 0.0345kg is the mass of 25L of the sample
