Ascorbic Acid
How many moles of carbon, hydrogen, and oxygen are present in ascorbic acid?
Ascorbic acid (vitamin C) contains 40.92 % carbon, 4.58% hydrogen, and 54.50% oxygen by mass. Assume a 100-g sample of ascorbic acid.
From the percentage values it's easy to calculate the mass of individual atoms:, e.g. in 100g ascorbic acid there is 40.92g of C atoms (since 40.92%). In the similar way, calculate the mass of other atoms present.
Now, divide the masses of the atoms (in grams) by corresponding atomic masses (in g/mol) to calculate number of moles of that atom present, e.g.
the number of moles of C = 40.92g/(12 g).
