A metal with a specific heat of 0.780J/g c requires 45.0 J of heat to raise the temperature by 2.00 c what is the mass of the metal

Answer 1

q = mC∆T

q = heat = 45.0 J

m = mass = ?

C = specific heat = 0.780 J/gº

∆T = change in temperature = 2.00º

Solving for m, we have ...

m = q / C∆T = 45.0 J / (0.780 J/gº)(2.00º)

m = 28.8 g (3 sig. figs.)
