Chapter 3 ATOMS AND MOLECULES

Q (a) Calculate the relative molecular mass of water (H2O). (b) Calculate the molecular mass of HNO3

Solution:(a) Atomic mass of hydrogen = 1u, oxygen = 16 uSo the molecular mass of water, which contains two atoms of hydrogen and oneatom of oxygen is = 2 × 1+ 1×16 = 18 u(b) The molecular mass of HNO3= the atomic mass of H + the atomic mass of N+ 3 × the atomic …
