Question

What is the molarity of a solution with 13.95 grams of solute and a volume of 400.0 mL? The solute has a molar mass of 273.2 g/mol.

Answer 1

Answer:

0.1277 M

Explanation:

13.95 g x 1 mole Solute    = 0.05106 mole solute

              273.2 g solute

400 mL = 0.4 L  

                                        0.05106 mole solute  = 0.1277 M

                                                  0.4 L
