Answer:
C5H10O5
Explanation:
The molecular formula is a multiple of the empirical formula. I.e
Molecular formula => [CH2O]n
[CH2O]n = 150
[12 + (2x1) + 16 ]n = 150
30n = 150
Divide both side by the coefficient of n i.e 30
n = 150/30 = 5
Molecular formula => [CH2O]n
Molecular formula => [CH2O]5
Molecular formula => C5H10O5
