An unknown metal is raised in temperature by 31oC by 691 J of energy. If the specific heat for the metal is 0.917 J/g*C, what is the mass of the sample?

Answer 1

q = mC∆T

q = heat =691 J

m = mass = ?

C = specific heat = 0.917 J/gº

∆T = change in temperature = 31º

Plug in the values and solve for m (in grams)

m = (691 J) / (0.917 J/gº)(31º) = answer
