Answer:

119.67 g

Explanation:

6.02×10^23 molecules of N2O = 44 g N2O

3.011×10^24 molecules of N2O

= (44×3.011×10^24) / 6.02×10^23

= 220.0730897 g N2O

mass of ethene =360 – (220.0730897+2.5)

=136.4269103 g ethene

Average molar mass of gaseous mixture

=(136.4269103+220.0730897+2.5) / 3

= 119.67 g
