mole is a unit that measures the amount of substance. It is one of the seven SI base units. Quantity: One mole of any substance contains exactly 6.022 x 10²³ particles (atoms, molecules, ions, etc.). This number is known as Avogadro’s number. Significance: Moles allow chemists to
ions When dealing with mixtures, you often need to: Identify the known quantities (mass, moles, concentration) Set up equations based on the conservation of mass or moles Solve for the unknowns using algebraic methods Approach to Solving Mix

of a Compound Question: What is the molar mass of calcium carbonate (CaCO₃)? Answer: Atomic masses: Ca ≈ 40.08 g/mol; C ≈ 12.01 g/mol; O ≈ 16.00 g/mol Molecular mass: \[ 40.08 + 12.01 + (3 \times 16.00) = 40.08 + 12.01 + 48.00 = 100.09 \text{ g/mol} \] Analysis: This calculation d
topes: Multiply the mass of each isotope by its percentage abundance (expressed as a 1. decimal). Sum these values. 2. For example, chlorine has two main isotopes: Chlorine-35 (75% abundance, atomic mass 34.97) Chlorine-37 (25% abundance, atomic mas
4.01 g/mol Mass = moles x molar mass = 3 mol x 44.01 g/mol = 132.03 g. 3. Conversion Between Particles and Mass Question: How many grams are in 1.2044 x 10²⁴ particles of water (H₂O)? Answer: Find moles: Number of particles / Avogadro's number = 1.2044 x 10²⁴ / 6.022 x 10²³ ≈ 2 mol Calculate ma
