Question 1

A piece of gold with a mass of 21.0 g was heated to 100.0 °C and placed inside a coffee cup calorimeter. The temperature of the water inside the calorimeter increased from 23.8 °C to 25.5 °C. The specific heat capacity of water is 4.184 J g-1 °C-1 and the specific heat capacity of gold is 0.129 J g-1 °C-1. Calculate the mass of water contained inside the calorimeter.
◦ 16.0 g
◦ 32.9 g
◦ 21.0 g
◦ 39.5 g
◦ 28.4 g

Question 2

A piece of uranium with a mass of 12.1 g and an initial temperature of 60.2 °C was placed inside a coffee cup calorimeter. The temperature of the water inside the calorimeter increased from 22.8 °C to 23.9 °C. The specific heat capacity of water is 4.184 J g-1 °C-1 and the specific heat capacity of uranium is 0.116 J g-1 °C-1. Calculate the mass of water contained inside the calorimeter.
◦ 8.4 g
◦ 11 g
◦ 17 g
◦ 1.2 g
