How many kJ of energy are needed to convert 600g of a mystery substance with a molar enthalpy of vaporization of 14.3kJ/mol and molar mass of 42g/mol?

put the answers   and i could answer.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

i dont know the answe

c. electrical charges of ionic bonds.
