The K sp of PbBr 2 is 6.60 × 10 − 6 . What is the molar solubility of PbBr 2 in pure water? molar solubility: M What is the molar solubility of PbBr 2 in 0.500 M KBr solution? molar solubility: M What is the molar solubility of PbBr 2 in a 0.500 M Pb ( NO 3 ) 2 solution?

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
