32g of anhydrous copper(ii)tetraoxosulphate(vi) dissolved in 1dm\(^3\) of water generated 13.0kj of heat. The heat solution is?
32g of CUSO\(_4\) liberate 13.0kj of heat
Molar mass of CUSO\(_4\) = 160g
No. of moles of CUSO\(_4\) = 32g
No. of moles = 32(mass) / 160(molar mass)
= 0.2 moles
i.e 0.2 = 13kj
1 moles = xkj
: 65KJ
There is an explanation video available below.
