0.82M concentration of ethanoic acid in vinegar
Therefore 1000cm3 of vinegar contains 0.82M
Therefore 1000cm3 of vinegar contains 0.82 moles x RMM
=0.82x 60
= 49.2g
1000cm3 of vinegar contains 49.2g
Therefore the percentage weight to volume is 4.92%
The percentage format is used because it is more likely that the customer will understand
percentages as opposed to moles.
