Define the calculated molar mass of the sulfate

Reference no: EM13647577

You order two primary standards of ultra pure K2SO4 (174.260 g/mol) and Na2SO4 (142.043 g/mol) for an experiment. When they are delivered, their labels are so damaged that you cannot tell which is which. You decide to perform a precipitation reaction to determine which bottle contains which compound. You re-label the containers A and B. You then take 0.1657 g of pure reagent from bottle A, dissolve it in 100.0 mL of water, and titrate it in a precipitation titration against 0.0424 M Ba2+. The volume of Ba2+ required to reach the endpoint is 22.40 mL.

a) What is the calculated molar mass of the sulfate present in bottle A?

What is the acceleration of the crate relative to the ground : A crate of mass 45.0 kg is being transported on the flatbed of apickup truck. The coefficient of static friction between the crateand the truck's flatbed is 0.350, andthe coefficient of kinetic friction is 0.240.

Explain the h2so4 is then titrated against naoh : One way to analyze sulfur is by comustion of the sample, which produces SO2 and SO3 that can be bubbled through H2O2 to produce H2SO4. The H2SO4 is then titrated against NaOH in the reaction H2SO4 + 2NaOH Na2SO4 + 2H2O
