The density at 20 0 C of a 0.500 M solution of acetic acid in water is 1.0042 g/mL. What is the molality of the solution? The molar mass of acetic acid, CH3CO2H, is 60.05 g/mol.
Let the volume of the acetic acid solution be 1 litre = 1000 mlthus, moles of acetic acid = molarity*volume of solution in litres = 0.5*1 = 0.5 molesnow, molar...

vinegar contains 5.00% acetic acid by mass and has a density of 1.01g/ml. What mass(in grams) of acetic acid is present in 5.00 L of vinegar?
The mass of vinegar is m(vinegar) = V(vinegar) * d(vinegar) = 5 L * 1.01 g/mL = 5050 g The mass of acetic acid is m(CH3COOH) = w(CH3COOH) * m(vinegar)...

Determine of pH of acid solutions like 0.1m hcl,0.5m hcl,0.025m hcl,0.0125m hcl by using quinhydrone and calomel electrode .compare the values of pH with theoretically calculated values.
pH = -lg [H + ]; 0.1m hcl: pH = 1; 0.5m hcl: pH = 0.3; 0.025m hcl: pH = 1.6; 0.0125m hcl: pH = 1.9.

At 298 K, a 0.100 M solution of acetic acid is 1.34% ionised. Calculate the ionisation
constant of acetic acid.
Ka = ɑ^2*C/(1 - ɑ); ɑ = 1.34% or 0.0134; C = 0.1 M. Ka = 0.01342 × 0.1 / (1 - 0.0134) = 1.8 × 10^{-5}. Answer: 1.8 ×...

If you take 109.7 mL of a 40.3 %(v) vinegar (acetic acid) solution, how many mL of acetic acid do you have?
v = Vsolute/Vsolution;Vsolute = Vsolution*v;Vsolute =109.7 *0.403 = 44.2 mL.Answer: 44.2 mL.

What is the pH of a solution containing 0.020 mol sodium hydroxide and 0.100 mol acetic acid dissolved in 100.0 mL of water, given that the pKa of acetic acid is 4.75?
In the solution, sodium hydroxide and acetic acid neutralize each other according to the equation:CH3COOH + NaOH → CH3COONa + H2OAs a result, as 0.020 mol sodium hydroxide interact with 0.100 mol acetic...

A photographic "stop bath" contains 160mL of pure acetic acid. HC2H3O2(1) in 650 mL solution. What is the v/v concentration of acetic acid in the stop bath?
Solution:acetic acid = HC2H3O2 - soluteVolume of acetic acid = 160 mLVolume of the solution = 650 mLv/v concentration = (solute volume / volume of the solution) × 100%v/v(HC2H3O2) =...
