Question

b) A piece of solid gold was heated from 274K to 314K using 55.7J of energy to raise the
temperature. What mass of gold was present?​

Answer 1

Answer:

Explanation:

So we know q = mc$\Delta$T.

q = 55.7 J

c = 0.129j/g°C

and $\Delta$T = 314-274 = 40°C.

and m is mass which can solve since we got every other variable. We will get m = 10.8g.
