Jack who weighs 68 kg is 45 years old and has severe hypomagnesaemia. He requires 0.26 g/kg of magnesium sulfate heptahydrate to be given intramuscularly over 4 hours. Magnesium Sulfate Concentrated Injection (2.465 g magnesium sulfate heptahydrate (MgSO4.7H₂O MWt = 246.5) in each 5 mL ampoule) is to be diluted to 40 %w/v with 0.9%w/v sodium chloride solution. Calculate the volume of 0.9% sodium chloride solution that would be required. (Answer to 1 decimal place.)
