You have a solution that is 18.5% (v/v) methyl alcohol. if the bottle contains 1.46 l of solution, what is the volume (v) in milliliters of methyl alcohol?

Answer : The volume of methyl alcohol is 270.1 mL

Explanation :

As we are given 18.5 % (V/V) methyl alcohol. That means, 18.5 mL volume of methyl alcohol present in 100 mL of solution.

Now we have to determine the volume of methyl alcohol in 1.46 L or 1460 mL solution.

As, 100 mL solution contains 18.5 mL of methyl alcohol

So, 1460 mL solution contains of methyl alcohol

Therefore, the volume of methyl alcohol is 270.1 mL

i'm pretty sure its b i might be wrong though!

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
