Question:

When 1243 J of heat energy is added to 44.3g of hexane, C6H14, the temperature increases by 12.4 degrees Celsius. Calculate the molar heat capacity of C6H14.

Answer: ____ J/(mol*Celsius)

HINT:

The units of molar heat capacity, J(mol*Celsius), imply the formula needed to calculate it.

Cp = q_p/(n(delta(T))

where q is heat energy (in joules), n is the number of moles, and deltaT is the temperature change (in degrees Celsius).
