A compound was found to contain nitrogen and oxygen in the ratio 28 gm...
Given:
- Nitrogen content in the compound = 28 gm
- Oxygen content in the compound = 80 gm
To find:
- The formula of the compound
Solution:
The ratio of nitrogen to oxygen can be used to determine the formula of the compound.
1. Finding the number of moles:
- The molar mass of nitrogen (N) = 14 g/mol
- The molar mass of oxygen (O) = 16 g/mol
- Number of moles of nitrogen = Nitrogen content / Molar mass of nitrogen = 28 gm / 14 g/mol = 2 mol
- Number of moles of oxygen = Oxygen content / Molar mass of oxygen = 80 gm / 16 g/mol = 5 mol
2. Simplifying the ratio:
- The ratio of nitrogen to oxygen is 2:5
- To simplify the ratio, divide both numbers by their greatest common divisor (GCD), which is 1 in this case.
- The simplified ratio is 2:5
3. Determining the formula:
- The ratio of 2:5 indicates that there are 2 moles of nitrogen for every 5 moles of oxygen in the compound.
- The formula of the compound can be written as N2O5, where the subscript represents the number of atoms.
Therefore, the correct answer is option C) N2O5.
- Nitrogen content in the compound = 28 gm
- Oxygen content in the compound = 80 gm
