Question

The student uses 25.0 cm3 of 1.60 mol / dm3 sodium hydroxide to prepare the crystals.
2NaOH(aq) + H2SO4(aq) + 8H2O(l) ------> Na2SO4.10H2O(s)
Calculate the maximum mass of hydrated sodium sulfate crystals that can be formed.

Answer 1

1. find out no of moles of NaOH used.
2. Find out no of moles of Na2SO4 produced from this value.(2 moles of NaOH gives one mole of sodium sulfate hydrate.
3. From the no of mles of sodium sulfate find out the weight of sodium sulfate..

Answer 2

Thanks! :)
