What is the molarity of a 50.0 mL solution that contains 0.0350 mol of sodium sulfate, Na2SO4?
0.007 mol/L
0.07 mol/L
0.0007 mol/L
0.7 mol/l

The molarity of a 50.0 mL solution that contains 0.0350 mol of sodium sulfate 0.7

Explanation:

Molarity is a concentration measure that indicates the amount of moles of solute that appear dissolved in each liter of the mixture.

So, the Molarity of a solution is determined by the expression:

Molarity is expressed in units ().

In this case:

Replacing:

Molarity= 0.7

The molarity of a 50.0 mL solution that contains 0.0350 mol of sodium sulfate 0.7
