Question
5. A solution of barium hydroxide, Ba(OH)2, contains 4.285 g of barium hydroxide in 100.0 mL of solution. What is the molarity of the solution?
As a rough estimate, 85 g divided by 75 g/mol is about 1 mol. If you divide 1 mol by 0.4 L you get 2.5 M. This approximation agrees with 0.4000 L ol/L = 2.85 M KCI O Verify your results. the answer of 2.85 M. PRACTICE 1 Vinegar contains 5.0 g of acetic acid, CH3COOH, in 100.0 mL of solution. Calculate the molarity of acetic acid in vinegar. If 18.25 g HCl is dissolved in enough water to make 500.0 mL of solution, what is the molarity of the HCl solution? 3 If 20.0 g H2SO4 is dissolved in enough water to make 250.0 mL of solution, what is the molarity of the sulfuric acid solution? A solution of AgNO3 contains 29.66 g of solute in 100.0 mL of solution. What is the molarity of the solution? A solution of barium hydroxide, Ba(OH)2, contains 4.285 g of barium hydroxide in 100.0 mL of solution. What is the molarity of the solution? What mass of KBr is present in 25 mL of a 0.85 M solution of potassium chloride? If all the water in 430.0 mL of a 0.45 M NaCl solution evaporates, what mass of NaCl will remain?
