Presentation on theme: "Avogadro’s Number: 1 mole = 6.02 x 1023 particles"— Presentation transcript:

1 Avogadro’s Number: 1 mole = 6.02 x 1023 particles -Particles can be atoms, molecules, formula units, ions, etc. Molar mass: the number of grams of a substance required to equal 1 mole of that substance -Use atomic masses from the periodic table to calculate molar mass STP gas relationship: at STP, 1 mole of gas = 22.4 L gas -STP (Standard Temperature and Pressure) = 0˚ C and 1 atm pressure Molarity: measure of concentration of a solution -moles of solute volume (in liters) of solution Molar ratio; numerical relationship between any 2 substances in a reaction Use coefficients from balanced equation
