Answer:
To find the molarity of a 5% vinegar solution, you first need to determine the mass of acetic acid in the solution. To do this, you can multiply the mass of the solution by the mass fraction of acetic acid.
The mass fraction of acetic acid in a 5% vinegar solution is 5%, or 0.05. The mass of the solution is the density of the solution multiplied by the volume of the solution. Since the density of the solution is 1.01 g/mL, you can use the following formula to calculate the mass of the solution:
Mass of solution = density * volume
Once you have the mass of the solution, you can use the following formula to calculate the mass of acetic acid in the solution:
Mass of acetic acid = mass of solution * mass fraction of acetic acid
Once you have the mass of acetic acid, you can use the molar mass of acetic acid to calculate the number of moles of acetic acid in the solution. Finally, you can use the volume of the solution to calculate the molarity of the solution using the following formula:
Molarity = number of moles / volume
