Witryna25 wrz 2024 · Find the normality of 0.321 g sodium carbonate in a 250 mL solution. To solve this problem, you need to know the formula for sodium carbonate. Once you realize there are two sodium ions per carbonate ion, the problem is simple: N = 0.321 g Na 2 CO 3 x (1 mol/105.99 g) x (2 eq/1 mol) N = 0.1886 eq/0.2500 L. N = 0.0755 N. Witryna15 wrz 2024 · In serial dilution, the density of cells is reduced in each step so that it is easier to calculate the concentration of the cells in the original solution by calculating the total dilution over the entire series. Serial dilutions are commonly performed to avoid having to pipette very small volumes (1-10 µl) to make a dilution of a solution.
