Question

Do you guys know how to solve the stochiometry problems for chemistry?
I don't have any specific problems, I just want to know the process to solve them so I could do them myself. For example, the 3.8 mol NH2 x 3 mol H2 / 2 mol NH3 x 2.02 g H2/ 1 mol =105 g H2. This was an example given by my teacher but I just want to know the process to understand how to do it.

Answer 1

Answer:

stochiometry is the calculation of reactants and products in chemical reactions. ... This means that if the amounts of the separate reactants are known, then the amount of the product can be calculated.

Explanation:

There are four steps in solving a stoichiometry problem:

1. Write the balanced chemical equation.

2. Convert the units of the given substance (A) to moles.

3. Use the mole ratio to calculate the moles of wanted substance (B).

4. Convert moles of the wanted substance to the desired units.
