Answer:
2.408 moles of hydrogen are in the sample.
Explanation:
Molecular formula of acetic acid = [tex]CH_3COOH[/tex]
Ratio of carbon to hydrogen :[tex]\frac{2}{4}=\frac{1}{2}[/tex]
Measured number of moles of carbon atoms = 1.204
Let the moles of hydrogen be = x
Number of carbon atoms in 1.204 mol = [tex]1.204 mol\times N_A[/tex]
Number of hydrogen atoms in x mol = [tex]x \times N_A[/tex]
As we know that ratio of carbon to hydrogen atoms is 1:2.
[tex]\frac{1}{2}= \frac{1.204 mol\times N_A}{x \times N_A}[/tex]
x = 2.408 moles
2.408 moles of hydrogen are in the sample.
