To calculate the heat capacity of 50 grams of water, we can use the formula:Heat capacity Q = mass m specific heat c change in temperature T In this case, we are given the mass m as 50 grams, the specific heat c as 4.184 J/gC, and the change in temperature T is not given, but we can still calculate the heat capacity per degree Celsius.Heat capacity Q = 50 g 4.184 J/gCHeat capacity Q = 209.2 J/CSo, the heat capacity of 50 grams of water at 25C is 209.2 Joules per degree Celsius.
