Question

The three quantities most often calculated in chemical problems are:

Answer 1

The three most frequently calculated quantities in chemical problems are mass, volume, and moles.

Step-by-step explanation:

Chemistry problems often involve calculations of quantities. The three most frequently calculated quantities in chemical problems are:

1. Mass: Calculating the mass of a substance involved in a chemical reaction.
2. Volume: Determining the volume of a gas involved in a reaction.
3. Moles: Calculating the number of moles of a substance in a reaction.

These quantities are important for stoichiometry, which is the quantitative study of the relationships between reactants and products in a chemical reaction. The applications of stoichiometry involve the use of gas laws when reactants or products are gases, as well as the conversion of mass to volume and volume to mass.
