can someone please help me with this 3 questions?
What is the molar solubility (in mol L') of a salt in pure water with general molecular formula MX2 (where M is a cation and X is an anion) that has Ksp = 7.70 x 10-9? You have 5 attempts at this question. Remember: if you want to express an answer in scientific notation, use the letter "E". For example "4.32 x 10" should be entered as "4.32E4". Answer: Check What...
