What is the molecular mass of hydrogen chloride?
4.5 moles of calcium carbonate are reacted with dilute hydrochloric acid.
What mass of calcium chloride is formed? [Relative molecular mass of calcium chloride is 111].
A metal M forms a volatile chloride contaning 65.5 % chlorine. If the density of the chloride relative to hydrogen is 162.5, find the molecular formula fo the chloride (M- 56).
