A student mixes 41.8g of ethanol at 15.8 C with 50.7 g of water at 49.2 C. If the resulting temperature of the solution is 28.4 C, what is the specific heat capacity of the ethanol?

2. Relevant equations

Given heat capacity of water already.

3. The attempt at a solution

let X = heat capacity of ethanol

38.4C = (41.8*15.8*X - 49.2*50.7*4.184)/(X*41.8+50.7*4.184)

i just rearranged and solved for X. I did get the correct answer, however it seems too ugly for a simple MC question.
