NH3 (MW = 17.034 g/mol)
Melting point = minus 77.73 degrees C
Boiling point = minus 33.34 degrees C
Heat capacity of liquid = 4.700 J/g/K
Heat capacity of gas = 2.060 J/g/K
Heat of vaporization = 23.40 kJ/mol
Find A, B and C (as far as 0 degrees C) and the total energy required (in that order) in Joules (express as 'J'). Assume 100.0 g of substance. A, B and C should have four significant figures.
When entering your values import your answer followed by a space then J
Example: 3450. J
Notice that in this particular example a decimal point was included after 3450 to indicate that the zero is significant. If the answer does not need a decimal do not include one.
