The final temperature of the mixture upon reaching thermal equilibrium is 26.0 C What is the mass of the silver block? Express your answer to two significant figures and include the appropriate units 104.7387 g Submit X Incorrect: Try Again: 5 attempts remaining Provide Feedback me anything

Explanation / Answer

Q = mc?T

Q = heat energy (Joules, J), m = mass of a substance (kg)

c = specific heat (units J/kg?K), ? is a symbol meaning "the change in"

?T = change in temperature (Kelvins, K)

Specific heat = 0.233 J/gm 0C

Heat lost by silver = heat gained by water

m x 0.233 x (26 -24.2) = 100 x 4.184 x (26-24.2)

m = 1795.7 gm

Hence Mass of aluminium is 1795.7 gm
