What Is The Molarity Of A Solution In Which 0.78 Grams Of NaCL Is Dissolved In 250ml Of Solution?

Step One: Convert grams to moles.
moles = mass/molar mass = 0.78/(23+35.5) = 0.0133

Step Two: Divide moles by liters to get molarity.
250ml = 0.25 liters

Step Three: Put values in equation.
Molarity=(moles of solute)/liters of solution
= 0.0133/0.25
= 0.0532
