Question

You are given a 0.955 gram per liter standard solution of Erythrosin B. The molar mass of Erythrosin B is 879.87 g/mol. a. What is the molarity of the standard solution? b. Using 5.00 ml of the standard solution and a 50.00 ml volumetric flask, you produce dilution A. What is the molarity of dilution A? c. Using 7.00 ml of dilution A and a 100.00 ml volumetric flask, you make dilution B. What is the molarity of dilution B?

Step 1

Given: - Mass of Erythrosin B = 0.955 g - Molar mass of Erythrosin B = 879.87 g/mol - Volume of solution = 1 L = 1000 mL Molarity = (mass / molar mass) / volume Molarity = (0.955 g / 879.87 g/mol) / 1 L Molarity = 0.001086 mol / 1 L Molarity = 1.086 M Show more…
