🤓 Based on our data, we think this question is relevant for Professor Ernst's class at UTAH.

# Solution: A silver block, initially at 56.1°C is submerged into 100.0 g of water at 24.2°C, in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 26.3°C.What is the mass of the silver block? Express your answer to two significant figures and include the appropriate units.

###### Problem

A silver block, initially at 56.1°C is submerged into 100.0 g of water at 24.2°C, in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 26.3°C.

What is the mass of the silver block?

Express your answer to two significant figures and include the appropriate units.

###### Solution

We’re being asked to determine the mass of the silver block in the given system.

We will use the heat released by the silver block to calculate its mass.

Recall that heat can be calculated using the following equation:

$\overline{){\mathbf{q}}{\mathbf{=}}{\mathbf{mc}}{\mathbf{∆}}{\mathbf{T}}}$

q = heat, J

+qabsorbs heat
–qloses heat

m = mass (g)
c = specific heat capacity = J/(g·°C)
ΔT = Tf – Ti = (°C)
