HELP ME PLEASE ASAP!! One cup of fresh orange juice contains 132 mg of ascorbic acid (vitamin C, C6H8O6).?

Molar mass of C₆H₈O₆ = (12.0×6 + 1.0×8 + 16.0×6) g/mol = 176.0 g/mol
No. of moles of C₆H₈O₆ = (132/1000 g) / (176.0 g/mol) = 0.00075 mol

Volume of the solution = 251.0 mL = 0.2510 L

Molarity of Vitamin C in organic juice = (0.00075 mol) / (0.2510 L) = 0.00299 M

Divide 0.132 g by the molecular weight of ascorbic acid. This give you moles.

Now divide by 0.2510 L and your answer will be in moles/liter (or molarity)
