A biology experiment requires the preparation of a water bath at 37.0 °C. The temperature of the cold tap water is 22.0 °C, and the temperature of the hot tap water is 55.0 °C. If a student starts with 90.0 g of cold water, what mass of hot water (in grams) must be added to reach 37.0°C? (Assume specific heats of cold and hot water to be the same). (Enter answer without units)
