What mass of copper, with a specific heat of 0.385, can be heated from 20° C to 136 by the addition of 12,350 Joules of heat? Round the answer to two decimal places.

Answer 1

q = mass Cu x specific heat Cu x delta T
12,350 = mass Cu x 0.385 x (136-20)
Solve for mass Cu. Post your work if you get stuck.
