Calculate the molar mass of a)water(H2O) b) nitric acid (HNO2) |
|
Answer» the molar Mass of water (H2O) can be calculated by adding the molar masses of the individual ELEMENTS present. Molar Mass of H2O = (2x1) + 16 = 2 + 16 = 18g/molThe molar mass of the chemical substance is equal to the SUM of the atomic mass of the individual atoms. Given Atomic mass of H = 1u Atomic mass of N = 14 U Atomic mass of O = 16u The molar mass of HNO3 is (1 × 1) +(1 × 14) + (16×3) = 63 u.Explanation: |
