Specific heat

Hi, I am stuck on this question and would really appreciate some pointers on how to solve it,

The specific heat capacity of the lava is 1600 J kg^-1 oC^1. when all the erupted lava cools from the eruption temperature of 1050 degrees Celsius to 15 degrees celsius, the heat released is 2 x 10 ^15 J.
I need to calculate a value for the total mass of lava that erupted.

Many thanks for any advice

Re: Specific heat

Use the definition of specific heat. It is the amount of heat involved in changing the temperature of unit mass of the substance by a unit amount.

And don't ask me why.
