calculate a value for the total mass of lava that erupted. give your answer in scientific notation.

plzzz some one help meeee....

i posted this question before and i still dont get how u work out the mass

Use the equation

(Heat release) = Mass x (specific heat) x (change in temperature)

Rearrange it algebraically to solve for the mass.

is this right ...in that case ..or where am going wrong !!

1600 J kg -1 °C -1 x 2 x 10 15 J x 1035 °C = 3.312 x 10 21 kgs
