Given that one cup = 254.6 mL
, calculate the molarity of vitamin C in orange juice.
To calculate the molarity of vitamin C in orange juice, we first need to determine the amount of vitamin C in one cup of orange juice.
Let's assume that the concentration of vitamin C in orange juice is 50 mg per cup.
Next, we need to convert the mass of vitamin C in one cup of orange juice to moles. The molar mass of vitamin C (ascorbic acid) is 176.12 g/mol.
50 mg = 0.05 g
0.05 g / 176.12 g/mol = 0.0002836 mol
Now, we can calculate the molarity of vitamin C in orange juice:
Molarity = moles of solute (vitamin C) / volume of solution (in liters)
Molarity = 0.0002836 mol / 0.2546 L
Molarity = 0.001115 M
Therefore, the molarity of vitamin C in orange juice is 0.001115 M.
