Answer:
Paraffin wax (or petroleum wax) is a soft colorless solid, derived from petroleum, coal or shale oil, that consists of a mixture of hydrocarbon molecules containing between twenty and forty carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C.
A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
Density is the mass divided by the volume of the object

you know denisty and you know mass so you can determine volume if you rearrange the formula

however, when you're doing the division, make sure the units match, since density is given in grams and mass is given in kilograms
once you have volume in cm3, convert that into "dl"
