Fill in the blanks according to the chemical reaction below to indicate how many molecules of each substance are present.
N2 + 3H2 + 2NH3
Substance
N2
H2
NH3
Molecules Present (Coefficient)

6.022 x 10^23 molecules of N2

18.066 x 10^23 molecules H2

12.044 x 10^23 molecules NH3

Explanation:

N2 + 3H2 --> 2NH3

one mole contains 6.022 x 10^23 molecules (Avogadro number)

N2: 1 mole N2 => 6.022 x 10^23 molecules of N2

H2: 3 moles H2 ==> 3 x 6.022 x 10^23 = 18.066 x 10^23 molecules H2

NH3 : 2 moles NH3 ==> 2 x 6.022 x 10^23 = 12.044 x 10^23 molecules NH3

coefficient of n2 is 1, coefficient of h2 is 3 and the coefficient of nh3 is 2
