Interpretation: The mass of nitrogen dioxide reacting with water to produce
Concept Introduction: The relation between the number of moles and the mass of a substance is as follows:
Here, m is mass and M is molar mass.
In 1 mol of a substance, there are
Explanation of Solution
The given reaction is as follows:
The number of molecules of nitrogen monoxide is
Since in 1 mol of a substance there are
Or,
Now, from the given reaction, 3 mol of nitrogen dioxide reacted with water to give 1 mol of nitrogen monoxide. Thus, for 0.083 mol of nitrogen monoxide, the number of moles of nitrogen dioxide required will be:
Now, the mass of nitrogen dioxide can be calculated from the number of moles and molar mass as follows:
Put the values,
Therefore, the mass of nitrogen dioxide will be 11.5 g.
