# Specific heat capacity of a mixture

• timelesstrix0
In summary, to find the heat capacity of the mixture of the three substances, you would take the mass fractions of each substance and multiply them by their respective heat capacities, then add the products together to get the overall heat capacity of the mixture. This concept is important to understand when analyzing mixtures of different substances and their properties.

so for one of my assignments i need to make a calculation which involves the mixture to be made of different types of substance... the heat capacity for each of the different unknown substances that were given:
substance 1 = 1250J/kg °C
substance 2 = 1130J/kg °C
substance 3= 4100J/kg °C

i need to find the heat capacity of the mixture of these 3 substances to carry on with the rest of the problem..
so my question is how do i get the heat capacity for the mixture?? if possible please explain like the concept behind it since i will hav to do a presentation on it and will hav to explain how i got the heat capacity of the mixture

If it is an "ideal solution," the heat capacity of the mixture is simply a weighted average of the heat capacities of the individual components (weighted in terms of mass fractions).
