IT is not 1.06 I just took the test and that was wrong.

Molarity of a solution is the molar concentration, which is the number of moles of solute in 1 L of solution.

the mass of glucose is - 125 g

number of moles of glucose - 125 g / 180.16 g/mol = 0.694 mol

the number of moles of glucose in 650.0 x 10⁻³ L - 0.694 mol

number of moles of glucose in 1 L - 0.694 mol / 650.0 x 10⁻³ L = 1.068 mol/L

molarity of glucose solution is 1.068 M
