Answer:
Explanation:
Pair 2.50g of O₂ and 2.50g of N₂
The atoms sample with the largest number of moles since the masses are the same would be the one with lowest molar mass according the the equation below:
Number of moles = [tex]\frac{mass }{molarmass}[/tex]
Atomic mass of O = 16g and N = 14g
Molar mass of O₂ = 16 x 2 = 32gmol⁻¹
Molar mass of N₂ = 14 x 2 = 28gmol⁻¹
Number of moles of O₂ = [tex]\frac{2.5}{32}[/tex] = 0.078mole
Number of moles of N₂ = [tex]\frac{2.5}{28}[/tex] = 0.089mole
We see that N₂ has the largest number of moles
Answer:
Pair A : 2.50 g N2 Pair B : 21.5 g n2 Pair C : 0.081 CO2
