A sample of NaNO3 weighing 0·38g is placed in a 50·0 mL volumetric flask. The flask is then filled with water to the mark on the neck. What is the molarity of the solution?
Molar mass of NaNO3 = 85 g mol-1
Calculate the molarity of NaOH in the solution prepared by dissolving its 4g in enough water to form 250mL of the solution.
Gram equivalent is given as =
Gram equivalent of NaOH =
Volume of solution = 250 mL
Normality is given as =
A solution is prepared by dissolving 5.3g of Na2CO3 in distilled water to give 500 mL of solution. Calculate the molarity of the solution.
