Why does Zimsec use 28 cubic decimetres for molar gas volume at rtp? Ever textbook I ever used, even google state the molar gas volume at rtp as 24 cubic decimetres. This value is supposed to be a constant, so why does Zimsec choose to use a different value?

First of all you need to understand what molar gas volume is. 

Molar gas volume is the volume occupied by 1 mole of any gas. 

When a gas is heated, it expands. In Zimbabwe, the room temperature is warmer than in Europe, which means 1 mole of a gas at room temperature in Zimbabwe occupies a larger volume. 

So, in Europe 1 mole of a gas at room temperature occupies approximately 24 dm3 but in Zimbabwe it occupies approximately 28 dm3.
