Summary:
- In a laboratory situation, it is common to determine the amount of a substance by finding its mass in grams.
- In this concept, we will focus on the type of problem where both the given and the unknown quantities are expressed in moles.
- The production of ammonia (NH3) from nitrogen and hydrogen gases is an important industrial reaction called the Haber process, after German chemist Fritz Haber.
- The most useful quantity for counting particles is the mole, so if each coefficient is multiplied by a mole, the balanced chemical equation tells us that 1 mole of nitrogen.
