Explanation:

There is some info missing. I think this is the original question.

One cup of fresh orange juice contains 127 mg of ascorbic acid (vitamin C, C₆H₈O₆). Given that one cup = 257.6 mL, calculate the molarity of vitamin C in orange juice.

Express your answer to an appropriate number of significant figures with the appropriate units.

Step 1: Convert the mass of ascorbic acid to grams

We will use the relationship 1 g = 1,000 mg.

Step 2: Calculate the moles corresponding to 0.127 g of ascorbic acid

The molar mass of ascorbic acid is 176.13 g/mol.

Step 3: Convert the volume of the solution to liters

We will use the relationship 1 L = 1,000 mL.

Step 4: Calculate the molarity of the solution

an honest friend. a friend who cares about me, and wont use me. a friend that i can trust. not someone who is fake

mark this brainliest lol i need one more.
