Use the molar heat capacity for aluminum from table 1 to calculate the amount of energy needed to raise the temperature of 260.5 g of aluminum from 0 c to 125 C

Unfortunately, you failed to include the table 1 from which the molar heat capacity of aluminum could have been obtained. However, as a general rule, the heat needed to raise the temperature of a certain substance by certain degrees is calculated through the equation,

H = mcpdT

where H is heat, m is mass, cp is specific heat capacity, and dT is change in temperature. From a reliable source, cp for aluminum is equal to 0.215 cal/g°C. Substituting this to the equation,

H = (260.5 g) (0.215 cal/g°C) (125°C - 0)

H = 7000.94 cal
