75.0 g of glucose (molar mass = 180 g/mol) is dissolved in 250 mL of solution. What is the molarity of this solution?

1.67 M

Explanation:

75.0 g *1 mol/180 g = (75/180) mol of glucose

250 mL = 0.250 L

(75/180)/0.250 = 1.67 mol/L =1.67 M

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

the objects have the same charge.
