Introduction to Stoichiometry: Grams to Grams Calculations
Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. Understanding these relationships is crucial for predicting the amount of reactants and products involved in a reaction, as well as for calculating the yield of a desired product.
In stoichiometry, the relationship between reactants and products is often expressed in terms of grams. The mass of reactants and products in a balanced chemical equation can be used to determine the stoichiometric ratio, which represents the mole ratio between the reactants and products.
This ratio can then be used to convert grams of reactants to grams of products and vice versa.
Grams to Grams Calculations, Intro to stoichiometry grams to grams worksheet answers
To convert grams of reactants to grams of products, follow these steps:
- Write a balanced chemical equation for the reaction.
- Identify the mole ratio between the reactants and products using the stoichiometric coefficients in the balanced equation.
- Convert the given mass of the reactant to moles using its molar mass.
- Multiply the number of moles of the reactant by the mole ratio to determine the number of moles of the product.
- Convert the number of moles of the product to grams using its molar mass.
For example, consider the reaction between 10.0 g of hydrogen (H 2) and 20.0 g of oxygen (O 2) to form water (H 2O):
“`
H2+ O 2→ 2H 2O
“`
The mole ratio of H 2to H 2O is 2:2, which means that for every 2 moles of H 2that react, 2 moles of H 2O are produced. To convert 10.0 g of H 2to grams of H 2O, we can use the following steps:
- Convert 10.0 g of H2to moles: 10.0 g H 2× (1 mol H 2/2.02 g H 2) = 4.95 mol H 2
- Multiply the number of moles of H 2by the mole ratio: 4.95 mol H 2× (2 mol H 2O/2 mol H 2) = 4.95 mol H 2O
- Convert the number of moles of H 2O to grams: 4.95 mol H 2O × (18.02 g H 2O/1 mol H 2O) = 89.2 g H 2O
Therefore, 10.0 g of H 2will react with 20.0 g of O 2to produce 89.2 g of H 2O.
