WebAnswer PROBLEM 6.1.3 Determine the molarity for each of the following solutions: 0.444 mol of CoCl 2 in 0.654 L of solution 98.0 g of phosphoric acid, H 3 PO 4, in 1.00 L of solution 0.2074 g of calcium hydroxide, Ca (OH) 2, in 40.00 mL of solution 10.5 kg of Na 2 SO 4 ·10H 2 O in 18.60 L of solution 7.0 × 10 −3 mol of I 2 in 100.0 mL of solution WebAug 22, 2014 · So, you would add 34 mL of 85 % phosphoric acid to enough distilled water to make a total of 500 mL. Note: The answer can have only two significant figures, because that is all you gave for the molarity of the dilute acid and the percent concentration of the concentrated acid. If you need more precision, you will have to recalculate.
