Answer:
74.566
Explanation:
C6H6 + 02 =6CO2 + 3H2O
2C6H6 + 15O2=12CO2 + 6H2O
mm of C6H6=(12x6)+(6x1)= 72+6 =78gram/mol
mass conc = 2x78=156
mm CO2= 12+(16x2)=
12+32= 44gram/mol
mass conc of CO2 = 12x44
= 528
from The equation
156g of C6H6=528g of CO2
22.031g of C6H6=Xg of CO2
therefore, Xg=
22.031 x 528/ 156
= 74.566g
Distance s=347 meters
time t=134 sec.
speed =s/t=347/134=2.5896 m/s nearly
The type of substance mass
I HOPE IT WILL HELP YOU.
I HOPE YOU WILL HAVE A GREAT DAY.
THANK YOU.
