CAIE A-Level Physics A2 15.1.2 Molar Qua…aining a

[Maximum number: 1]

A sealed vessel contains a mass of 0.0424 kg of an ideal gas at $227^{\circ} \mathrm{C}$ . The pressure of the gas is $1.37 \times 10^{5} \mathrm{~Pa}$ and the volume of the gas is $0.640 \mathrm{~m}^{3}$ .

Calculate:

the mass of one molecule of the gas

mass =kg [1]

mass $=0.0424 /\left(1.27 \times 10^{25}\right)$ $=3.34 \times 10^{-27} \mathrm{~kg}$
