Ifl Lab S ? be detern rlng the flthip chimr a ompany,n9 vario phase changes Pre-lab assignnleflt you wIll go through soru of the caIcuI.,tlon% ??quired for Part 2 of this experiment In which you detem,,ne of ace, To determine ot ice you will C$stlally add ice to water, allow the Ice to melt, and nc temperatu change of the water. Lets first get an idea of the ratio of water to ice that you w need. The value for the H%fl of Ice Is 6.0 ki/mol. 1ers suppose you start with 36.9 g of,ce. 1.. DetermIne AH for meltIng 36.9 g of Ice. 12300) ou are correct. Our receipt no. is 157-3694 p TheS k you add the 36.9 g of Ice to water at a no lab (25?C). Ice to a minimum amount of water to melt all of the ice, what will the fir ter ?n the calonmeter be after all of the ?ce has meltetl? , PuIrjeExplanation / Answer
Answer:
Specific heat capacity of Ice (Cice) = 2.1kJ/kg.K
Specific heat capacity of water (Cwater) = 4.18kJ/kg.K
(Cwater)/(Cice) = (mass of water)/(mass of ice)
4.18/2.1= (mass of water)/36.9
mass of water = (4.18*36.9)/2.1
= 73.448 grams
