The conversion factor is added to the original given unit so that you can end up with the final unit. Basically, the conversion unit does not change the value because the factor is just equal to 1. You just manipulate the units by cancelling them.
Among the given choices, the fraction which is equal to 1 is 10⁻³ g/ 1 mg, because there are 1,000 mg per 1 g. In reverse, that would be 10⁻³ of a gram.
Answer:Methyl benzoate has a very high boiling point i.e. 199°C.Therefore a water-cooled condenser is not advisable as it might crack the condenser tube.So in such cases air condenser tube is normally used for such distillation procedure.
