How do I measure an amount of Vitamin C in orange juice?

I'm currently doing a science fair project on Vitamin C in orange juice, but I don't know how to measure the amount of Vitamin C that orange juice has. My science fair question was " What type of orange juice contains the most Vitamin C". Please help me out. Thank you!!!

Look on the label on the back of the orange juice container. It should tell how much Vitamin C it contains.
