A salt solution has a volume of 250 mL and contains 0.70 mol of NaCl. What is the molarity of the solution? Chemistry Solutions Molarity 1 Answer Nathan L. May 19, 2017 Answer: #2.8 M# Explanation: Molarity is a measure of the concentration of a substance expressed in the quantity of solute in moles per liter of solution: #M = (mol solute)/(L soln)# #250mL# is equal to #0.250L#, so our molar concentration is #M = (0.70 molNaCl)/(0.250Lsoln) = 2.8 M# Related questions what is the molarity of 20.0 ml of a KCl solution that reacts completely with 30.0 ml of a 0.400 M ...
