A mouthwash contains 22.5% (v/v) alcohol. If the bottle of mouthwash contains 355 mL, what would be the volume, in milliliters, of the alcohol?
The two occuring isotopes of gallium-69 and gallium-71,which are found in the ratio of 3:2. Determine the atomic mass of gallium.
If I add 0.495 g of solid calcium in a cup and of 100.0mL of deionized water. What is the inital moles of Ca in the cup
Suppose a mixture of helium and neon gases is collected over water at 28.0°C and 745 mmHg. Explain if the partial pres- sure of helium is 368 mmHg, Explain what is the partial pres- sure of neon and vapor pressure of water at 28°C 5 28.3 mmHg.
What kind of experimental conditions do you think you would need in order to carry out the reverse reaction. (The preparation of ester from an acid and alcohol)
The titration required 21.62 ml to turn he solution clear. What was the concentration of the iodate in the solution? What was the Ksp that the student determined for the titration?
Calculate the change in pH when 7.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq).
41.89 mL of NaOH were required to completely titrate 25.00 mL of a weak monoprotic acid. After 11.90 mL of sodium hydroxide had been added to the solution, the pH of the solution was 6.81. Calculate K_a_ and pK_a_ for this weak acid.
Calculate the pH during the titration of 10.00 mL of 0.400 M hypochlorous acid with 0.500 M NaOH. First what is the initial pH (before any NaOH is added)? The Ka for HOCl is 3.0 x 10-8 M.
