A 215 g sample of a substance is heated to 330 degrees C and then plunged into a 105 g aluminum calorimeter cup containing 165 g of water and a 17 g glass thermometer at 12.5 degrees C. The final temp is 35.0 degrees C. What is the specific heat of the substance?

Please show some effort of your own other than changing a letter in your name each time you post.
(1) Look up the specific heats of glass, aluminum and water.
(2) Compute the amount of heat energy gained by those three materials as they heat from 12.5 to 35 C. Call that heat Q.
It equals the heat lost by the sample.
(3) Q = M(sample)*C(sample)*295C
Solve for the specific heat C of the sample.
