We can use the ideal gas equation to determine the temperature with the given conditions of mass of the gas, volume, and pressure. The equation is expressed
PV=nRT where n is the number of moles equal to mass / molar mass of gas. Substituting the given conditions with R = 0.0521 L atm/mol K we can find the temperature
Chlorine is used as a disinfectant to wastewater treatment
plants. The addition of chlorine to the final treated water is because to make
sure that some of the microorganisms not killed during treatment is eliminated.
It is consumed before it is released to the environment to ensure that
microorganisms and other marine life are not killed in the process too.
In the titration of acetic acid with a strong base NaOH, the concentration of acetic acid is determined using the volume and molar concentration of NaOH used for titrating the vinegar solution. NaOH and acetic acid react in 1:1 mole ratio.
When a drop of the strong base, dispensed from the buret sticks to the walls of the Erlenmeyer flask but is not washed into the flask containing vinegar, it means that the recorded value of NaOH dispensed will be higher than the actual value required for the titration. So, the reported moles of acetic acid calculated from the moles of NaOH used for the titration will be higher. So, the mass percent reported will be higher than the actual value.
Answer: 0.428%
Explanation: % Error = [(measured - Actual)/Actual]*100%
(93.9g - 93.5 g)/93.5g = 0.428%
