An isolated insulated cylinder contains 15.40 grams of neon gas and a 62.30-gram bronze medal in thermal contact. When the bronze medal was put into the cylinder, its temperature was 72.30°C. The final temperature of both the medal and the neon gas is 66.30°C. Neon's specific heat capacity is 1.047 joules/gram degree Celsius, and bronze's specific heat capacity is 0.3770 joules/gram degree Celsius. What was the initial temperature of the neon? Type the correct answer in the box. Use numerals instead of words. Express your answer to the correct number of significant figures. The initial temperature of the neon gas was °C.
