A substance has a specific gravity of 108 and a vapor densit

A substance has a specific gravity of 1.08 and a vapor density of 1.4. What is the vapor volume of this substance in ft3/gal? State your answer rounded to one decimal place.

Solution

The molar mass of substance would be = vapor density * 2 = 2.8 g

specific gravity = 1.08 implies that density of substance is 1.08 g/cm³

Now, volume of vapor would be : Mass/ density = 2.8/ 1.08 = 2.592 cm³ = 6.8 * 10^-4 ft³/gal
