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...
