Answer:
The answer is "10.84 g".
Explanation:
The formula for calculating the number for moles:
In the given acid nitric:
Owing to the nitric acid mass =
Nitric acid molar weight
If they put values above the formula, they receive:
In the given chemical equation:
In this reaction, 2 mols of nitric acid are produced by 1 mole of water.
So, 1.204 moles of nitric acid will be produced:
We are now using Equation 1 in determining the quantity of water:
Water moles
Water weight molar
I think the correct answer from the choices listed above is option 3. The atomic mass of an element is defined as the weighted average mass of that element's naturally occurring isotopes. <span>The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu.</span>

Answer:
The formula would be: C₆H₈O
Explanation:
The mass of carbon dioxide formed = 627.4 mg
The percentage of carbon in the sample would be:
% carbon =
Where
44 is the molar mass of carbon dioxide.
The percentage of hydrogen in the sample would be:
% Hydrogen =
Rest will be oxygen = 100 -[74.92+8.33]=16.75
Let us calculate the moles of each of the elements present:
moles of carbon =
moles of hydrogen =
moles of oxygen =
The mole ration of carbon, hydrogen and oxygen = C:H:O = 6 : 8 : 1
so the formula would be:
C₆H₈O
