Computing percentage concentration of H2SO4
Posted: Thu Jan 28, 2021 8:07 am
175.0 g pure \(H_2O\) was placed in a beaker and thereafter 9.80 g pure \(H_2SO_4\) was added and stirred. What is the total volume of the solution and what is the percentage concentration of \(H_2SO_4\) in the solution?
My answer: 1.0 ml= 1.0 g \(H_2O\) Hence 175.0 g pure\(H_2O\)=175.0 ml\(H_2O\)
9.80 g \(H_2SO_4\)=5.36 ml because density of \(H_2SO_4\) is \(1.8302 g/cm^3\)
Hence total volume of the solution= 175 +5.36 =180.36 ml and % conc. of \(H_2SO_4= \frac{5.36}{180.36}=2.97 \)%
Is this answer correct?
