Molar Mass, Molecular Weight and Elemental Composition Calculator Enter a chemical formula to calculate its molar mass and elemental composition: Molar mass of MgSO4*H2O is 138.3829 g/mol of a chemical compound, More information on When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. NCERT Solutions Class 9 to 12 all subjects. Question 1: Calculate the molecular mass of the following: (i) H2O (ii) CO2 (iii) CH4 Answer.

6H2O Atomic mass of H=1u Atomic mass of O=16u Now, for H2O there are 2 Hydrogens and 1 oxygen So multiply the mass of Hydrogen with 2, mass of Oxygen with 1 and add both 1*2+16*1=2+16=18 2 The atomic weight of hydrogen is 1.00797 and for oxygen the atomic weight is 15.9994. So the molar mass of H2O is 15.9994 + (2 x 1.00797) which equals 18.01534 grams/mole.
