Calculate the molar mass of the following substances:
(a) Ethyne, C2H2
(b) Sulphur molecule, S8
(c) Phosphorus molecule, P4 (atomic mass of phosphorus = 31)
(d) Hydrochloric acid, HCl
(e) Nitric acid, HNO3
Calculate the molar mass of Sulphur molecule, S8
Given the atomic masses of S = 32u
calculate molar mass and number of molecules for five moles of sulphuric acid.
