Naturally occuring chlorine has two isotopes, Cl-35, which has an atomic mass of 34.969 amu and Cl-37. If the average atomic mass of chlorine is 35.46 amu and its natural abundance is 75.53%, what is the atomic mass of the Cl-37 isotope?
What is the volume of one mole of hydrogen gas at 273 K and 760 torr? What is the volume of one mole of oxygen gas under the same conditions?
How many grams of lithium are required to completely react with 60.7 mL of N2 gas at STP?
What is the pH of concentrated sodium hydroxide? NaOH FW=40.0 g/mol
When the reaction that occurs finally ceases, what will be the mass of unreacted copper in the bar? What will be the mass of silver metal that "plates out" of solution (that is, what mass of silver metal is produced by the reaction)
If someone can go in depth into finding the Ka to this and then guiding me through the rest of the steps, I'd be eternally grateful
