Thermochemistry ( solution calorimetry) Can someone help me with these problems?

.

.

1) Mgso4 + water

MgSO4 -----> Mg + SO4

mass of mgso4 :9.60 g

volume of water used : 250 ml

initial temprature of water : 21.10 C

final temperature : 22.50

calculate the total mass of solution

calculate ΔT of solution

.

.

2) Mg + HCL Mg +2H ---->Mg + H2

mass of solid : 14 g

Volume of HCL used : 300 ml

initial temprature : 22.60

final temp of solution : 28 C 1.

Calculate total mass of solution ( mass of acid + mass of solid)

2.Calculate ΔT of solution

3.Calculate number of moles of solid
