the mass of 0.52 moles of water is 9.3g...so that would be..9.3-0.52=8.78.I don't get it after that

14.1g ZnSO4.xH2O after heating mass formed is 4.4g or 0.03mole after heating mass driven off is 9.3g or 0.52 mole you said take the mass of 0.52 mole of water(9.3g) and subtract it from 14.1g that will give 4.8g.... after that im lost

is the answer 17..

thank u..i will definitely come back on this site!!!
