PDF	Stoichiometry of Chemical Reactions This chapter will describe how to symbolize chemical reactions using chemical equations how to classify some common chemical reactions by identifying patterns

Thus, to calculate the stoichiometry by mass, the number of molecules required for each reactant is expressed in moles and multiplied by the molar mass of each to give the mass of each reactant per mole of reaction.
The mass ratios can be calculated by dividing each by the total in the whole reaction.

How do you do chemical calculations?

Step 1: Find the moles of each element using the equation moles = mass / Mr.
Step 2: divide each of the moles by the smallest number calculated.
Here, the smallest number of moles is that of oxygen, with 0.025.
Step 3: write out the empirical formula using the ratio calculated.

How to do Stoich calculations?

Almost all stoichiometric problems can be solved in just four simple steps:

1Balance the equation.
2) Convert units of a given substance to moles.
3) Using the mole ratio, calculate the moles of substance yielded by the reaction.
4) Convert moles of wanted substance to desired units.

How do you calculate the mole ratio?

To calculate the molar ratios, you put the moles of one reactant over the moles of the other reactant.
Usually, you divide each number in the fraction by the smaller number of moles.
