V) By adding 5 g of a solute to 200 ml of 3% solution containing the same solute, what is the % concentration of the new solution? (vi) How much sterile liquid needs to be added to 100 ml of 10% solution to reduce its concentration by half? 46 Chapter 3 (vii) 12 mg of a drug are dissolved in 50 ml of sterile £uid and 25 ml then used for an injection. A further 25 ml of sterile £uid are then added to the unused 25 ml of original solution. Calculate the % concentration of the ¢nal solution.

A C Fractional equations such as  can be simpli¢ed using a B D technique known as cross-multiplication. This involves multiplying the bottom of the left hand side by the top of the right hand side and multiplying the bottom of the right hand side by the top of the left hand side. In the above example, after cross-multiplication the equation becomes: AÂDBÂC In order to make A the subject and dispose of D on the left hand side, divide both sides by D: Therefore AÂD BÂC  D D The Ds on the left hand side can also be cancelled: Therefore AÂ1 BÂC AÂ1  but, A 1 D 1 Basic Principles Therefore A  31 BÂC D To make B, C, or D the subject, exactly the same process is followed.
