Answer:

Molarity= 1.69M

Explanation:

m= 14.8, Mm= 35, V= 0.25dm3, C= ?

Moles = m/M= C×V

Substitute and Simplify

m/M= C×V

14.8/35= C×0.25

C= 1.69M

Is this equation completely balanced? 2C8H8 + 25O2 8CO2 + 18H2O No, because the number of carbon, hydrogen &amp; oxygen atoms on
Sergio039 [100]
<span>So to make it clear let's break the equation down species by species and assess the number of each species on bothe sides of the equation:
                   2C</span>₈H₈  +  25O₂   →   8CO₂ +  18H₂<span>O
LHS:  C - 16                                           RHS:  C - 8
          H - 16                                                     H - 36
          O - 50                                                    O - 34

Thus based on that it is evident that the equation is not quite balanced.  This therefore means a "</span><span>No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal."

</span>The actual balance equation would be C₈H₈  +  10O₂   →   8CO₂ +  4H₂O
