Molar mass N₂O = 14 x 2 + 16 => 44.0 g/mol

1 mole ---------- 44.0 g
moles ------------ 0.203 g

 0.203 / 44 => 0.004613 moles

1 mol N2O <span>contains 2 atoms N , therefore:

0.004613 x 2 => 0.009226 moles of N

hope this helps!</span>

To calculate the number of moles of an element in the given mass of a compound, we need to convert mass into moles by using its molecular eight then relate the ratio of the elements.

0.203 g N2O (1 mol / 44.01 g N2O) ( 2 mol N / 1 mol N2O) = 9.23 x 10^-3 mol N

The atoms of which elements are least likely to form chemical bonds? Check all that apply.
svetoff [14.1K]
The elements that apply are argon, neon and helium. These elements are called inert gasses and have unique properties that make them unreactive. These elements are so unreactive that they are classified as chemically inert.
The elements belong to a group in the periodic table known as the Noble Gases. They belong to family 18 of the periodic table and have atoms with 8 valence electrons. This configuration causes the gases to be unreactive.
