Question

I don't understand where to start first. Can you break it down for me?

Ascorbic acid, also known as vitamin C, has a percentage composition of 40.9% C, 4.58% H, and 54.5% O. The molar mass of ascorbic acid is 176.1 g/mol. Determine the empirical and molecular formulas
bobpursley
assume 100 grams, then find the moles of C, H, O from that.

Then divide each of those moles by the smallest moles of C, H, O.

You should end up with the ratio of the elements. Now, take the empirical formula mass, divide it into the mole mass given, it will tell you what to multiply the ratio by.
Ok Thankyou so much for breaking it down. I think I got it. (:
