To get the volume of the original solution in the dilution, we consider the dilutions that were made:
from 50 mL to 250 mL:
<span>1/5 of original was present</span>
<span>from 20 mL of 250 mL:</span>
<span>1/12.5 of the diluted mixture was presetn</span>
<span>So, V=50 mL*(1/5)*(1/12.5)= 0.8 mL of original bleaching solution was present in dilution</span>
