The heat needed to raise the temperature of 50g of substance by 15 c is calculated as follows

Heat = mc delta T

m= mass (50g)
c= specific heat capacity (0.92)
delta T= change in temperature( 15 c)

heat is therefore= 50 x 0.92 x 15 = 690

Nb: my answer has no units since the given specific heat capacity has no units
