Question

calculate average molecular weight of the mixture of 25percent CH4 and 75 percent SO2 by volume

Answer 1

Answer:

your answer is here mate

Answer 2

Answer:

Let mass of mixture is 100g  

then, mass of CH4 = 25% of 100g = 25g

mass of SO2 = 75% of 100 = 75 g

Average molecular weight formula -->  

sigma(% abundance molecular wt. of constituent)/100  

Therefore, (25×16) + (75×64)/100  

= 5200/100  

= 52
