The data given below was recorded when metal M was completely burnt in air. M is not the actual symbol of the metal. (RAM M = 56.0, O=16)
Mass of empty crucible and lid = 5.240g
Mass of crucible, lid and metal m = 5.352g
Mass of crucible, lid, metal oxide = 5.400g
(a) Determine the mass of
(i) Metal m
(ii) Oxygen.
(b) Determine the empirical formula of the meat oxide.

(a) (i) Mass of metal m
= 5.352 - 5.240g = 0.112g
(ii) Mass of oxygen
= 5.400 - 5.400 - 5.352 = 0.048g
b) Empirical formula
