how do i solve these chemistry problem?

Question

1] A 380. g aluminum engine part at an initial temperature of 3.15°C absorbs 86.2 kJ of heat. What is the final temperature of the part (c of Al = 0.900 J/gK)?

2] When 184 mL water at 20.°C is mixed with 76 mL water at 82°C, what is the final temperature? (Assume that no heat is lost to the surroundings and that the density of water is 1.00 g/mL.)

Answer 1

haha
buddy
even i was not able to solve chemistery
so it was a mistery for me for the whole 12th grade
