When 1903 J of heat energy is added to 48.2 g of ethanol, C2H6O, the temperature increases by 16.1 ∘C. Calculate the molar heat capacity of C2H6O.

Explanation:

molar heat capacity Cp

Q = nxCp x ΔT

n is no of moles , ΔT is rise in temperature , Q is heat added

48.2 g of ethanol = 48.2 / 46 moles = 1.0478 moles

n = 1.0478

Putting the values

1903 = 1.0478 x Cp x 16.1

Cp = 112.8 J / mole °C

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
