Answer:
56.28 g
Explanation:
First change the grams of oxygen to moles.
(50.00 g)/(32.00 g/mol) = 1.5625 mol O₂
You have to use stoichiometry for the next part. Looking at the equation, you can see that for every 2 moles of H₂O, 1 mole of O₂ is produced. Convert from moles of O₂ to moles of H₂O using this relation.
(1.5625 mol O₂) × (2 mol H₂O/1 mol O₂) = 3.125 mol H₂O
Now convert moles of H₂O to grams.
(3.125 mol) × (18.01 g/mol) = 56.28125 g
Convert to significant figures.
56.28125 ≈ 56.28
Explanation:
In case of methyl alcohol , i.e. , CH₃OH ,
counting the equivalent protons , there are three protons of the methyl group at are all equivalent , and shows the chemical shift at 3.4 - 4.0 ppm , there is the increase in the chemical shift value due to the presence of an electronegative oxygen atom .
And there is one more hydrogen atom in the alcoholic functional group , and this hydrogen will also show a chemical shift at 5.0 - 5.5 ppm .
Therefore ,
Methyl alcohol will show two signals due to methyl proton and another due to OH hydrogen .
