Questions & Answers

Q: What are the three types of conversions involved in stoichiometry?

The three types of conversions in stoichiometry are: moles to moles, moles to grams, and grams to grams. These conversions are used to convert between different substances in a chemical reaction.

Q: How do you determine the molar ratio in stoichiometry?

The molar ratio is determined by the coefficients in the balanced chemical equation. For example, if the balanced equation is 2A + 3B -> 4C, the molar ratio between A and C is 2:4, or 1:2.

Q: What is the process for converting moles to grams in stoichiometry?

To convert moles to grams, you need to know the molar mass of the substance. Multiply the number of moles by the molar mass to get the grams.

Q: How do you balance a chemical equation in stoichiometry?

To balance a chemical equation, adjust the coefficients in front of the formulas to ensure that the number of atoms of each element is the same on both sides of the equation.

Summary & Key Takeaways

• Stoichiometry involves converting between different substances in a chemical reaction.

• The three types of conversions in stoichiometry are: moles to moles, moles to grams, and grams to grams.

• The process involves using molar ratios, balancing chemical equations, and using molar masses.
