Chapter 6: Calculate the molar Mass the following 1. CH4 C = 1 x 12g/mol = 12 g/mol H = 4 x 1 g/mol = 4 g/mol CH4 = 16 g/mol 2. H2O H = 2 x 1 g/mol = 2 g/mol O = 1 x 16 g/mol = 16 g/mol H2O = 18 g/mol 3. MgBr2 Mg = 1 x 24 g/mol = 24 g/mol Br = 2 x 80 g/mol = 160 g/mol MgBr2 = 184 g/mol 4. H3PO4 H = 3 x 1 g/mol = 3 g/mol P = 1 x 31 g/mol = 31 g/mol O = 4 x 16 g/mol = 64 g /mol H3PO4 = 98 g/mol 5. Ca(OH)2 Ca = 1 x 40 g/mol = 40 g/mol O = 2 x 16 g/mol = 32 g...
