In stoichiometry, how many grams are produced?
Actually, it may not really be direct to answer the question and just tell the exact number of grams gotten from stoichiometric reactions. but each product gotten is dependent on the specific chemical reactions.
In stoichiometry, the amount of products produced solely depends really on the balanced chemical equation for the reaction and the amounts of reactants used.
The application of Stoichiometry allows us to calculate the amount of product that should be produced based on the amounts of reactants used and the stoichiometric coefficients of the balanced chemical equation.
It is important to understand how to solve stoichiometry problems step by step and also tips on how to determine the limiting reagent.
The stoichiometric coefficients used in solving stoichiometric problems represent the mole ratio between the reactants and products in a balanced chemical reaction.
After using the mole ratio to get the number of moles of reactant or product requested, it is then important to convert the amount of product produced to grams.
To do this, we need to know the molar mass of the product. The molar mass is the mass of one mole of the substance, which is the sum of the atomic masses of all the atoms in the molecule.
Once we know the molar mass of the product, we can use the following formula to convert the amount of product from moles to grams:
mass (in grams) = moles x molar mass
Ultimately, the number of grams produced in stoichiometry depends on the specific reaction and the amounts of reactants used and can be calculated using the stoichiometric coefficients and the molar mass of the product.
Steps in determining how many grams produced in stoichiometry.
To determine the number of grams produced in stoichiometry, you will need to follow these steps:
- Write a balanced chemical equation for the reaction.
- Determine the number of moles of the reactant you have.
- Use stoichiometry to determine the number of moles of the product that will be produced.
- Convert the number of moles of the product to grams using the molar mass of the product.
Here’s an example:
Suppose you want to determine how many grams of CO2 will be produced when 2.5 moles of CO react with excess oxygen gas (O2) according to the following balanced chemical equation:
2CO+ O2 → 2CO2
- Write the balanced chemical equation: 2CO+ O2 → 2CO2
- Determine the number of moles of reactants and products
- Use stoichiometry to determine the number of moles of CO2 that was produced by 2.5 moles of CO
- Convert the number of moles of CO2 to grams using the molar mass of CO2
2CO+ O2 → 2CO2
If 2 moles of CO===2 moles of CO2
2.5 moles of CO===x
x = 2.5 x 2/2 = 2.5 moles of CO2
convert to mass
1 mole of CO2 ====== 44g
2.5 moles of CO2 ==== X
X = 2.5 X 44 = 110 grams of CO2
Therefore, 110 grams of CO2 will be produced when 2.5moles of CO gas react with excess oxygen gas.
In conclusion, the amount of grams produced from stoichiometric equations is dependent on the specific equation you are using as reference.
