What is the molar concentration of 3.5 mol of KCl dissolved in 750. mL of solution? (HINT: You MUST convert from mL to L)

Ibelieve the answer 4 moles

13 protons and 14 neutrons.  this also means that the amount of electrons also is 13 because electrons have the same amount as protons..the atomic number means the amount of protons (which effectively tells you the electrons) the atomic mass, tells you the amount of protons and neutrons in the nucleus.hope this . 

Ais your answer hope it

I’m not sure about this
