calorimeter?

Question

If adding a 0.552g sample of metal x to 150 ml of 1.0 M HCl caused a temperature increase of 7.33 degrees celsius, calculate the quantity of heat thas flowed.

Answer 1

Assumed: 1.0M HCL is about equal to

The specific heat of water (1 calorie/gram °C = 4.186 joule/gram °C).

The specific heat of the metal is negligible.

(150 ml = 150grams) * 4.186 J/g = 628 J/C

628 J/C * 7.33 = 4.6 kJ
