Mole mole calculations are not the only type of calculations that can be performed using balanced chemical equations recall that the molar mass can be determined from a chemical formula and used as a conversion factor. Place your final answer in the formula mass column chemistry computing formula mass worksheet problem set up example find the formula mass of cano32 ca 1 x 401 401 relationship between moles and hence mass and volumes can be used to solve problems of. In chapter 5 you learned to balance chemical equations by comparing the numbers of each type of atom in the reactants and products the coefficients in front of the chemical formulas represent the numbers of molecules or formula units depending on the type of substance here we will extend the meaning of the coefficients in a chemical equation. Chemistry quantitative relationships in chemical equations when we balance a chemical equation we are satisfying the law of conservation of mass that is we are making sure that there are the same number of atoms of each element on both sides of the equation. 34 mass relationships in chemical equations converting amounts of substances to moles and vice versa is the key to all stoichiometry problems whether the amounts are given in units of mass grams or kilograms weight pounds or tons or volume liters or gallons we just used the balanced chemical equation to calculate the
