32g of anhydrous copper(ii)tetraoxosulphate(vi) dissolved in 1dm3 3 of water generated 13.0kj of heat. The heat solution is?

32g of anhydrous copper(ii)tetraoxosulphate(vi) dissolved in 1dm${}^3$ of water generated 13.0kj of heat. The heat solution is?

Answer Details

32g of CUSO${}_4$ liberate 13.0kj of heatMolar mass of CUSO${}_4$ = 160gNo. of moles of CUSO${}_4$  = 32gNo. of moles = 32(mass) / 160(molar mass)= 0.2 molesi.e 0.2 = 13kj1 moles = xkj: 65KJ
