1c The experimentаl results оf аnоther student were used in the equаtiоn shown to calculate the enthalpy change, ΔH, for dissolving one mole of NH4Cl in excess water.     ΔH = m ×c ×ΔT                  n = +14 500 J mol–1      In the equation: m = mass of solution = 50 g c = specific heat capacity of water = 4.18 J g–1 °C–1 ΔT = maximum temperature change of solution  n = moles of NH4Cl   1c(i) State two assumptions made in this calculation. You do not need to justify your answers or do a calculation. (2)
