We’re being asked to determine the empirical formula of ascorbic acid composed of C, H, and O, given the mass percent of C, H and O.
Recall that the empirical formula is the simplest whole-number ratio formula of a compound.
For this problem, we need to do the following steps:
Step 1: Calculate the mass and moles of C, H, and O in the compound.
Step 2: Determine the lowest whole number ratio of C, H, and O to get the empirical formula.
The elemental mass percent composition of ascorbic acid (vitamin C) is 40.92% C, 4.58% H, and 54.50% O.
Determine the empirical formula of ascorbic acid.
