How many moles of carbon, hydrogen, and oxygen are present in a 100-g\rm g sample of ascorbic acid?
ascorbic acid is C6H8O6.
mols ascorbic acid in 100 g is
mol = grams/molar mass = 100/176.12 = ?
There are 6 C atoms/mol acid, 8 H atoms/mol acid, and 6 O atoms/mol acid.
mols C is 6x that.
mols H is 8x that.
mols O is 6x that.
