MM Zn(NO₃)₂ = 189.36 g/mol
mass 1 mol Zn(NO₃)₂ = 189.36 g
mass hydrate = 100 / 63.67 x 189.36 = 297.409 g
mass 1 mol hydrate = 297.409 g
MM hydrate = 297.409 g/mol
MM hydrate = MM Zn(NO₃)₂ + MM xH₂O
297.409 = 189.36 + x(18)
x = 6
Yes what do u need help with
Decomposition is the example of a reaction in which hydrogen and oxygen are produced by running an electric current through water.
Decomposition of water through electrolysis of water into oxygen and hydrogen gas due an electric current passed through water. when an electric current is passed through water, oxygen gas is being produced at the anode and hydrogen gas is produced at the cathode.
