The  heat  required  to heat 9.61g  of ethanol from  24.1 c to 67.3  c  is  calculate as below

Q(heat) = M(mass) xC (specific heat  capacity )  x  delta T (bhange in temperature)

Q=?
M=9.61 g
C= 2.46 j/g/c
deltaT =67.3c - 24.1 = 43.2 c

Q is therefore= 9.61 g  x 2.46 j/g/c x 43.2 c = 1021.27  joules
