0.800 g of a metal Y (RAM = 40) reacted with 40.0 cm3 of 1.00 mol dm-3 hydrochloric acid to produce a neutral solution of Y chloride and 480 cm3
of hydrogen gas (H2) collected at room temperature and pressure.
Evaporating the solution to dryness produced 2.22 g of solid Y chloride.
(a) Find the empirical formula for Y chloride.
(b) Use the given information to construct the equation for the reaction.
(Cl = 35.5. Molar volume of a gas at rtp = 24.0 dm3)
