Question

If a concentrated solution of acetic acid is 99.5 % HC 2 H 3 O 2 and has a density of 1.05 g/mL, what is the concentration of this acid in moles per litre?

Answer 1

The concentration of this acid in moles per litre : 17.41

Further explanation

Given

99.5% acetic acid

density=ρ=1.05 g/ml

Required

the concentration (mol/L)

Solution

99.5% dan density 1.05 g/ml (MW acetic acid = 60 g/mol)

`\tt 99.5\%* 1.05(g)/(ml)* (1000~ml)/(L)=1044.75~g/L\\\\(1044.75~g/L)/(60~g/mol)=17.41~mol/L`
