the mass of the crucible is 19.73 g fill the crucible with CuSO4 which was 26.44 g Heat the crucible until the water is released it weighed 23.40 g So now, how many moles of water is removed? The number of moles of CuSO4 that after dissolution rest? determine the number of H2O molecules, namely x, that is bound in CuSO4? set the equation for the decomposition reaction? find the correct value of x at. Calculate the percentage? is the hydration of CuSO4 exo-or endothermic?
So you want someone to do all of this? Show what you know to do and explain what you don't understand about the rest of the problem.
