The subscript indicates the amount of hydrogen there is, H2O, meaning there are 2 hydrogens.
Answer:
CHO₂
Explanation:
The following data were obtained from the question:
Carbon (C) = 26.68%
Hydrogen (H) = 2.24%
Oxygen (O) = 71.08%
Empirical formula =?
The empirical formula of the compound can be obtained as follow:
C = 26.68%
H = 2.24%
O = 71.08%
Divide by their molar mass.
C = 26.68 /12 = 2.223
H = 2.24 / 1 = 2.24
O = 71.08 / 16 = 4.4425
Divide by the smallest.
C = 2.223 / 2.223 = 1
H = 2.24 / 2.223 = 1
O = 4.4425 /2.223 = 2
Thus the empirical formula of the compound is CHO₂
The conversion factor for volume at STP is
or
. Since we want volume, we would use
. We conclude with the following calculations:
The answer is 9.744L H2
