A piece of glass has a temperature of 72.0 °C. Liquid that has a temperature of 37.0 °C is poured over the glass, completely covering it, and the temperature at equilibrium is 50.0 °C. The mass of the glass and the liquid is the same. Ignoring the container that holds the glass and liquid and assuming that the heat lost to or gained from the surroundings is negligible, determine the specific heat capacity of the liquid.

You need more information. You need the specific heat of the glass in order to calculate the specific heat of the liquid. The information you provided will only tell you the ratio of speciic heats
the specific heat of the glass is 840 J/kg*C, it's in one of the tables in the book but it's really stupid how they don't give that with the problem
