Question

1718 l of a 0.3556-m c3h7oh solution is diluted to a concentration of 0.1222 m, what is the volume of the resulting solution

Answer 1

Answer : The volume of the resulting solution will be 0.4999 L.

Explanation : As the two molar concentration of the $C_{3} H_{7}OH$ solution are given and one of the volume concentration needs to be found.

So, according to the formula :-  $m_{1}V_{1} = m_{2}V_{2}$

And here if we consider $V_{1}$ as 0.1718 L moles and $m_{1}$  as 0.3556 moles then we need to find $V_{2}$ as $m_{2}$  is given as 0.1222 moles.
Hence on solving the formula we get,  

 $V_{2}$ = (0.1718 X 0.3556) / 0.1222 = 0.4999 L
