1) The molar mass is the mass (g) of one mole of a chemical. The molar mass (g/mol) can be calculated by adding the atomic masses of the constituent atoms in the formula of a chemical. a) Find molar mass (MM) of Ca,O,N,S,He,Ar,Ag b) Find the molar mass of H2,O2,Cl2,P4,S8 2) Find number of moles from mass: mole (mol)=molarmassmass a) Find the mole of 37.56g of H2O b) Find the mole of 24.25g of C12H22O11 (table sugar) c) Find the mole of 12.05g of NaCl (table salt) d) Find the mole of 0.02530g of HCl
