The molar specific heat of copper is 24.5 J/(mol.K).The amount of heat needed to raise 126 g of copper by 2C $\circ$ is

Question

Quizplus · Accepted Answer

First, we need to convert the mass of copper from grams to moles:
126 g Cu x (1 mol Cu / 63.55 g Cu) = 1.98 mol Cu

Next, we can use the formula q = mCΔT to calculate the amount of heat needed:
q = (1.98 mol)(24.5 J/(mol·K))(2°C) = 98 J

Therefore, the answer is D) 98 J.
