Just use the formula:
Q = cMΔT
where
Q = heat energy needed for that material to get desired temperature change (in Joules)
M = mass (in grams) so you have to convert from kilograms.
c = specific heat constant for the material being heated [in /(grams oC)]
ΔT = change in temperature (in oC)
Q = (1.75)(2.17 x 1000)(191 - 23) = (1.75)(2170)(168) = 637,980 Joules
hope that helps you in some way
also have a great day!
