Which of the following represents the correct relationship between moles, mass, and molar mass?
Correct Answer: mass = moles × molar mass
- Step 1: Understand what moles are. Moles measure the amount of substance.
- Step 2: Know what mass is. Mass is how heavy something is, usually measured in grams.
- Step 3: Learn about molar mass. Molar mass is the mass of one mole of a substance, usually in grams per mole (g/mol).
- Step 4: Recognize the relationship. The formula that connects moles, mass, and molar mass is: mass = moles × molar mass.
- Step 5: Use the formula. If you know the number of moles and the molar mass, you can calculate the mass.
