Question

If the molarity of acetic acid in vinegar is 0.837M, calculate:



The mass (g) of acetic acid per liter of vinegar (MW acetic acid = 60.05g/ml)

The mass(g) vinegar per liter of vinegar (density vinegar = 1.005g/ml)

The weight % (g acetic acid per liter/g vinegar per liter) of acetic acid in vinegar

Answer 1

\[Molarity = \frac{amount of moles}{volume}\]

Answer 2

To be clear, your molecular weight of acetic acid is 60.05 g/mol.

Answer 3

So to find the mass per Liter of acetic acid,
.837 mol/L*(60.05 g/1 mol) = ? g/L

Answer 4

Can you try to find the mass of vinegar per Liter using its density?
