Typical white vinegar purchased from a grocery store is 510

Typical white vinegar purchased from a grocery store is 5.10% by mass acetic acid in water. Calculate the volume of .100 M NaOH needed to titrate 25 mL of store bought vinegar

Solution

molar mass of acetic acid = 60g

let mass of solution = 1000g

mass og acetic acid = 51g

density of water = 1000g/L

moles of acetic acid = 51/60 = 0.85

molarity (M1) = 0.85 M (moles/L)

V1= 25ml

M2 = 0.1M

M1*V1=M2*V2

V2 = 212.5 ml
