How to find the empirical formula for Fructose |
|
Answer» ong>Answer: Explanation: The EMPIRICAL formula is the simplest whole number ratio defining constituent atoms in a species. In all of these problems it is useful to ASSUME 100
g of compund, and calculate the ATOMIC composition. So, in 100 ⋅ g fructose, there are: 40.00 ⋅ g 12.01 ⋅ g ⋅ m o l − 1
=
3.33 ⋅ m o l ⋅ C , 6.72 ⋅ g 1.00794 ⋅ g ⋅ m o l − 1
=
6.66 ⋅ m o l ⋅ H , 53.29 ⋅ g 15.999 ⋅ g ⋅ m o l − 1
=
3.33 ⋅ m o l ⋅ O , If we divide thru by the smallest molar quantity, we GET a formula of C H 2 O . The molecuar mass of fructose is 180.16 ⋅ g ⋅ m o l − 1 . How do we use these data to provide a molecular formula? |
