The molar ratio of nitrogen to ammonia from the balanced equation is 1:2. This means that if 400 cm 3 of nitrogen are used then we will form double that volume of ammonia.

Provided some additional information is known, one value can be deduced from the other using the equations below. Molarity equations To calculate molarity or to calculate related values (including ...

The molar volume is equal to 24 dm 3 (24,000 cm 3). This volume is given in questions that need it.
