Question

A calorimeter contains 70.2 g of water at 15.3 ° C . If 143.7 g of water at 36.5 ° C is mixed with it, the common temperature becomes 28.7 ° C . The water equivalent of the calorimeter is, 15.6 g, 9.4 g, 6.3 g, 13.4 g

MARKS App · Accepted Answer

Let m be the water equivalent of the calorimeter. Then, 70.2 + m 28.7 - 15.3 = 143.7 36.5 - 28.7 m = 13.4 g
