Solution the spinal fluid sample contains roughly 4 mg of glucose in 5000 mg of fluid, so the mass fraction of glucose should be a bit less than one part since the solution density isn't greatly different from that of water (1 g/ml), a reasonable estimate of the hcl mass in 500 g (0.5 l) of the solution is. Keep in mind, this is the total volume of the solution, not the volume of solvent used to dissolve the solute. Molarity = moles of solute/liters of solutionliters of solution = moles of solute/molarityliters naoh = 3.25 moles naoh/2.5 m naoh= 1.30 liters as an example, 1m naoh solution contains 40g of naoh in one litre of water (1000g) and thus the concentration would be 4% naoh. Molarity = number of moles of naoh/ volume of solution in litre. How many grams of lioh is needed to make 250 ml of a 0.33 m lioh solution?
