Question

What is the volume of 1.8 moles of chlorine gas at STP

Answer 1

STP stands foor standard temperature and pressure, and it is used with the assumintion that the gas behaves as an ideal gas. These conditions are standardized nowadays as temperature of 0°C and pressure of 1 bar.

In this conditions, the volume is directly proportional to the number of moles of the gas.

1 mol in STP conditions occupy 22.7 L.

Using rule of three, we have:

1.8 mol --- V

1 mol --- 22.7 L

`\begin{gathered} (1.8)/(1)=(V)/(22.7L) \\ V=1.8\cdot22.7L \\ V=40.86L\approx41L \end{gathered}`
