At 100°C, water and methylcyclohexane both have vapour pressures of 1 atm. Also at 100°C, the latent heats of vaporisation of these compounds are 40.63 kJ/mole for water and 31.55 kJ/mole for methylcyclohexane. The vapour pressure of water at 150°C is 4.69 atm. At 150°C, the vapour pressure of methylcyclohexane would be expected to be

Stoichiometry
Specific gravity on API scale is given by the relation(where, G = specific gravity at 15.5°C).

°API = (140/G) - 130

°API = 200(G - 1)

°API = (141.5/G) - 131.5

°API = 145 - (145/G)

°API = (140/G) - 130

°API = 200(G - 1)

°API = (141.5/G) - 131.5

°API = 145 - (145/G)
