Homework Help: Chemistry

Posted by Susie on Tuesday, February 10, 2009 at 8:13pm.

The molecular weight of glucose is 180.2 and the molecular weight of lactose is 342.3. What is the molarity of a 25% glucose solution? What is the molarity of a 25% lactose solution?

I know that molarity = mol/L or mol/1000 mL and that molecular weight is g/mol. But I'm not sure where to go from there.
