Question

36g of asprinis burnt with a flame in presence of excess oxygen until nothing remains.the byproduct cases are collected and it is found that there are 79.2g of pure CO2 as one of the products.how many carbon atoms are there in each formula unit of asprin(MW=180g)

Answer 1

CO2+ H2O → C6H12O6+ O2

36/180= 0.2mol

0.2× 6.022× 10²³

= 1.2044×10²³ atoms
