Question:

There are two cylinders containing methane gas and Nitrogen dioxide gas.

The volume of these two cylinders is 500cm³ and 700 cm³ respectively. Calculate the number of moles of each gas and the total number of mole of the gaseous mixture when the two cylinders are connected together.

Answer:

$$n_1 = \frac{V}{V_m} = \frac{0.5L}{22.4L} = 0.022 \text{ moles of methane}.$$ $$n_2 = \frac{V}{V_m} = \frac{0.7L}{22.4L} = 0.03125 \text{ moles of nitrogen dioxide}.$$ $$n_{\text{total}} = 0.022 + 0.03125 = 0.053 \text{ moles}.$$
