Attempt 1 Together, a pure gold ring and a pure titanium ring have a mass of 16.36 g. Both rings are heated to 73.90 °C and dropped into 15.6 mL of water at 21.30 °C. The water and the rings reach thermal equilibrium at a temperature of 25.91 °C. The density of water is 0.998 g/mL. The specific heat capacity of water is 4.18, the specific heat capacity of gold is 0.129 and the specific heat capacity of titanium is 0.544 Calculate the mass of each ring. 4.51 mass of gold ring: 8 Incorn mass of titanium ring: 11.85 Incorrect 8
Question 12 of 18 > An eager scientist on a hot summer day needs to determine how much ice to buy. She has a cooler which is filled with 34 cans of soda at a temperature of 84.1°F. Each can has a mass of 405 g. The scientist wants the temperature of the drinks to be 38.7"F. If there is no heat lost by the cooler and ignoring any heat lost to the soda containers, what mass mice of ice needs must she add to her cooler? Assume the temperature of the ice is 32.0 F. The latent heat of fusion for ice is 80.0 cal/g, the specific heat of water is 1.00 cal/g-"C, the specific heat of the soda is 0.900 cal/g-"C, and there are 454 grams per pound. 6489.5 lbs Mice= Incorrect
