How many milliliters of water at 25.0°C with a density of 0.997 g/mL must be mixed with 189 mL of coffee at 93.3°C so that the resulting combination will have a temperature of 63.7°C? Assume that coffee and water have the same density and the same specific heat (4.18 J/g•OC) across the temperature range.
