Answer 2

Answer:

CH2O...

Explanation:

To find the ratio in moles you divide by the A RATIO of each element.

USING APPROXIMATE VALUES:

RATIO IN GRAMS C:H:O = 40:6.7:53.3

RATIO ON MOLES           = 40/12 : 6.7/1 : 53.3/16

                                         = 3.33 : 6.7 : 3.33

HENCE, DIVIDING THROUGH BY 3.33 =

1:2:1

SO,

therefore, the empirical formula =

 CH2O...
