5. you have 100 kg of gas of the following composition: ch4 - 30% h2 - 10% n2 - 60% what is the average molecular weight of this gas?

21.8 g/mol

Explanation:

Molecular weight of CH4 = 16g/mol

H2 = 2g/mol

N2 = 28g/mol

(16*30 + 2*10 + 28*60)/100

=2180/100

=21.8g/mol

idk

explanation:

dasdad

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this
