Answer:
the name of time remaining the same is true and send you doing this kit for Sandhya
Explanation:
and % carbon in C6H12O6 = 72.06 × 100 % = 40.0 % by mass. 180.18 Similarly, the percentage of hydrogen and oxygen can be calculated as follows: ... glucose, so the mass of oxygen in 1 mole of glucose = 6 × 16.00 g = 96.00 g.
An empirical formula is a formula that shows the elements in a compound in their lowest whole-number ratio. Glucose is an important simple sugar that cells use as their primary source of energy. Its molecular formula is C6H12O6. Since each of the subscripts is divisible by 6, the empirical formula for glucose is CH2O.
The empirical formula of a compound is the simplest whole number ratio of atoms of each element in the compound. For example, the molecular formula of glucose is C 6H 12O 6 but the empirical formula is CH 2O. ...
