Final answer:
To find the moles of nitrogen in 0.237 g of N₂O, calculate the moles of N₂O using its molar mass and then multiply by 2, as each molecule of N₂O contains two atoms of nitrogen.
Step-by-step explanation:
To determine the number of moles of nitrogen in 0.237 g of N₂O, we first need to calculate the molecular mass of N₂O. The molar mass of nitrogen (N) is 14 g/mol, and the molar mass of oxygen (O) is 16 g/mol. Therefore, the molecular mass of N₂O is (2×14) + (1×16) = 44 g/mol.
Next, we use the formula:
Number of moles = mass (g) / molar mass (g/mol)
For N₂O, this becomes:
Number of moles of N₂O = 0.237 g / 44 g/mol
This calculation will give us the moles of N₂O. Since there are 2 moles of Nitrogen in each mole of N₂O, we need to multiply the moles of N₂O by 2 to find the moles of Nitrogen (N).
Finally, we'll calculate the moles of N:
Number of moles of N = (Number of moles of N₂O) x 2
By completing the calculations, you will have the moles of nitrogen (N) present in 0.237 g of N₂O.
