    There are 0.01 moles of N in 0.209 g of N₂O.

    Explanation:

    Given dа ta:

    Mass of N₂O = 0.209 g

    Moles of N = ?

    Solution:

    Number of moles of N₂O = Mass / molar mass

    Number of moles of N₂O = 0.209 g / 44 g/mol

    Number of moles of N₂O = 0.005 mol

    Since one N₂O have two N atom because it is diatomic.

    0.005 mol * 2 = 0.01 mol

    There are 0.01 moles of N in 0.209 g of N₂O.
