Question

5. What is the volume of hydrogen chloride formed from 50 mL each of hydrogen and chlorine? Assumes
volumes of the gases have been measured at the same temperature and pressure
​

Answer 1

Answer:

The important thing to notice here is that the reaction takes place at STP conditions, which are defined as a pressure of

100 kPa

and a temperature of

0

∘

C

.

Moreover, at STP one mole of any ideal gas occupies exactly

22.7 L

- this is known as the molar volume of a gas at STP.

Since all the gases are at the same conditions for pressure and temperatur
