Consider a sample of 24.24 g of a solid initially at 0.0 °C. How
much energy in kilojoules is required to melt the solid and warm it
to 64.15 °C? Properties: melting point = 0.00 °C boiling point =
122.9 °C molecular weight = 26.820 g/mol heat of fusion (ΔHf) =
12.93 kJ/mol specific heat capacity of liquid (Cs) = 3.438 J/gC
Note: Treat this problem just like you would a problem with ice and
water but using the above constants. I have changed the problem to
avoid online calculators providing a means of cheating on the
problem. You should report your answer to this problem to four
significant figures.
