1) The molar mass of H2.
The molar mass of H is 1.008 g/mol.
2*1.008 g/mol = 2.016 g/mol
2) The molar mass of Mg(OH)2.
The molar mass of Mg = 24.30 g/mol
The molar mass of O = 15.99 g/mol
The molar mass of H = 1.008 g/mol
Mg = 1*24.30 g/mol = 24.30 g/mol
O = 2*15.99 g/mol = 31.99 g/mol
H = 2*1.008 g/mol = 2.016 g/mol
The molar mass of Mg(OH)2 is equal to 24.30 g/mol + 31.99 g/mol + 2.016 g/mol
58.3197 g/mol
3) The molar mass of NH4Cl
The molar mass of N = 14.01 g/mol
The molar mass of H = 1.008 g/mol
The molar mass of Cl = 35.45 g/mol
The molar mass of NH4Cl is equal to 14.01 g/mol + (4*1.008 g/mol) + 35.45 g/mol = 53.4915 g/mol.
4) The molar mass of Carbon dioxide (CO2)
The molar mass of C = 12.01 g/mol
The molar mass of O = 15.99 g/mol
The molar mass of CO2 is equal to 12.01 g/mol + (2*15.99 g/mol) = 44.01 g/mol.
5) The molar mass of copper (II) sulfate (CuSO4)
The molar mass of Cu = 63.55 g/mol
The molar mass of S = 32.06 g/mol
The molar mass of O = 15.99 g/mol
The molar mass of CuSO4 is equal to 63.55 g/mol + 32.06 g/mol + (4*15.99 g/mol) = 159.61 g/mol.
6) The molar mass of silver nitrate (AgNO3)
The molar mass of Ag = 107.87 g/mol
The molar mass of N = 14.01 g/mol
The molar mass of O = 15.99 g/mol
The molar mass of AgNO3 is equal to 107.87 g/mol + 14.01 g/mol + (3*15.99 g/mol) = 169.87 g/mol
