Question

in a gaseous mixture 2mol of CO2 , 1 mol of H2 and 2 mol of CO are present than determine the average molecular mass?​

Answer 1

Answer:

Moles of Co2, H2 He respectively

2,1,2

mole percentage of co2=

__2___ =__2__=0.4×100 =40%

2+1+ 2 5

moles percentage of co2 is 40%

Answer 2

Answer:

29.2

Explanation:

co2 m1= 12+32=44   moleno = 2

h2 m2=2 moleno=1

co m3=28 moleno=2

molecular mass avg=(m1.n1+m2.n2+m3.n3)/n1+n2+n3=146/5=29.2
