Q: What is the most useful quantity for counting particles?


Read this paragraph and choose the correct option from the provided answers:

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 reacts with 3 moles of hydrogen to produce 2 moles of ammonia. This is the conventional way to interpret any balanced chemical equation.

 Choices:

- the coefficient

- the periodic table

- the vector

- the mole


A:
the mole
