Answer to Question #291673 in General Chemistry for owo chu

Question

1.    The specific heat capacity of zinc is 0.388 J/g.˚C. Calculate the initial temperature of zinc block of mass 38g if the amount of heat supplied to it was 220 J and the maximum temperature reached by the zinc block was 55˚C. 

Answer 1

Q= mc∆T

220= 38×0.388×(x-328)

220=14.744x-4836.032

14.744x=5056.032

X=342.92K
