The price of gold is $625 per troy ounce at this writing. How much heat (in J) is needed to raise the temperature of $5000.00 worth of gold from 29.5 oC to 70.5 oC?

(1 troy oz = 31.10 g and the specific heat of Au is 25.42 J/(moloC).)

Please help!

$625/oz x ?oz = $5,000.
? oz x 31.1 g/oz = x grams.
q = grams x specific heat x (Tfinal-Tinitial)
Substitute and solve for q.
