Hey I have a bit of problem which I just can't wrap my head around, if anyone can help it would be much appreciated.

To prevent scurvy you need the minimum daily requirement of 60mg of Vitamin C (C6 H8 O6)

If 10g of Spinach is found to contain 1.2x10^-5 of vitamin C, how much spinach must be eaten to have the minimum requirement?

You're going to need to include the actual units from the problem for the vitamin C

I'm assuming 1.2x10^-5 refers to moles, there wouldn't be another unit that would make sense. If that's the case, just convert the 60 mg into grams and then use the molar mass of vitamin c (x amount of moles of vitamin c/grams of vitamin c) to find the moles of vitamin c you need per day to prevent scurvy. Then simply divide that number by 1.2x10^-5 to get how many servings of 10g of spinach you need.
