A sample of an infusion was diluted 10 ml to 250 ml and then 10 ml to 200 ml. It was then analysed and was found to contain sodium at 0.789 mg/100 ml. Calculate the concentration of sodium in the original sample in %w/v. The sample was composed of a mixture of sodium lactate and sodium carbonate in equimolar amounts. Calculate the amount of sodium lactate and sodium carbonate in mg/10 ml of the sample (Na = 23, lactate = 89, carbonate = 60)

A sample of an infusion was diluted 10 ml to 250 ml and then 10 ml to 200 ml. It was then
analysed and was found to contain sodium at 0.789 mg/100 ml. Calculate the concentration
of sodium in the original sample in %w/v. The sample was composed of a mixture of sodium
lactate and sodium carbonate in equimolar amounts. Calculate the amount of sodium
lactate and sodium carbonate in mg/10 ml of the sample (Na = 23, lactate = 89, carbonate =
60)
