q = mass metal x specific heat metal x delta T
58 = 18 g x specific heat x 35
58/(18*35) = ?
What do you think it is?
A metal is thought to be copper or gold. When 18 g of the metal absorbs 58 cal, its temperature rises by 35 °C.
a. What is the specific heat, in cal/g °C, of the metal?
b. Would you identify the metal as copper or gold?
The table we were given says:
Copper, Cu(s) : .0920 cal/g °C
Gold, Au(s) : .0308 cal/g °C

Thank you so much!
58/18 * 35 = 0.0920, which is copper.
58/18 * 35 = 0.0920, which is copper.
