Please help me solve this questions for solution concentratrions. I don't really know how to get to the answer.
1) Calculate the molarity of a solution made by dissolving 123.4 g of sodium sulfate (Na2SO4) in enough water to form 525.0mL of solution.
2) What is the molarity of a solution that is made by dissolving 13.68g of sucrose (C12H22O11) in sufficient water to form 225.0mL of solution?
3) Calculate the molarity of a solution made by dissolving 15.00 g of glucose (C6H12O6) in sufficient water to form exactly 200mL of solution.
4) What is the molar concentration of each ion present in a 0.225 M aqueous solution of calcium nitrate?
5) What is the ratio of the concentration of potassium ions to the concentration of carbonate ions in a 0.1275 M solution of Aluminium carbonate?
6) What is the molar concentration of K+ ions in a 0.0175 M solution of potassium Phosphate?
7) How many grams of Na2SO4 are required to make 1.250 L of 0.800 M Na2SO4?
8) What is the concentration of ammonia in a solution made by dissolving 13.75 g of ammonia in 8.0 L of water?

10) What volume of 1.00M stock solution of glucose must be used to make 200.0mL of a 2.75x10â2M glucose solution in water?
11) (a) What volume of 2.80 M lead(II) nitrate solution contains 0.550 mol of Pb2+? (b) How many milliliters of 5.0 M K2Cr2O7 solution must be diluted to prepare 550 mL of 0.20 M solution? (c) If 20.0 mL of a 10.0 M stock solution of NaOH is diluted to 250 mL, what is the concentration of the resulting stock solution?
12) Glacial acetic acid with density 1.049 g/ml â Calculate the molarity if 20.00 ml of glacial acetic acid dissolved in enough water to produce 250.00 ml of the solution.
13) Glycerol, C3H8O3, with density of 1.2656 g/ml. Calculate the molarity of a solution of glycerol, when 50.00 ml of glycerol dissolved in enough water to make 500.00 ml of the solution.
