A sample of solid silver releases 476 J of heat when cooled from 98.3°C to 21.2°C.The specific heat of silver is 0.24 J/g • °C.What is the mass of the sample?

Question

Quizplus · Accepted Answer

The mass can be calculated using the formula q = mcΔT, where q is the heat released, m is the mass, c is the specific heat, and ΔT is the change in temperature. Solving for m gives m = q / (cΔT) = 476 J / (0.24 J/g°C * (98.3°C - 21.2°C)) = 25.7 g.
