Honors Chemistry Worksheet 1: Mass-Moles-Particles - A worksheet designed to teach students how to convert between mass, moles, and particles using stoichiometry.

Final Answer:
1. One mole is defined as 6.02 × 10²³ particles (Avogadro’s number).
2. True
3. The mole is a counting unit, whereas grams is a mass unit.
4. Coefficients in a balanced chemical equation can be used with moles for setting up ratios.
5. To convert from grams to moles: divide by molar mass.
6. To convert from moles to grams: multiply by molar mass.
7. To convert from moles to molecules: multiply by Avogadro’s number.
8. To convert from molecules to atoms: multiply by the number of atoms per molecule.
9. The molar mass of a compound is found by adding the atomic masses of all atoms in the formula and is known as g/mol.
10.
 a. 15.0 g of H₂O = 0.833 mol
 b. 221.0 g of H₂SO₄ = 2.25 mol
