If the concentration of Na3PO4 in a solution is 0.11 M and there is 31mL of solution, how many sodium ions are in the solution?

Question

australopithecus · Answer

First find the moles present in the solution

next create a ratio of molecular masses and multiply it by the moles in solution

(Molecular Mass of Na3/Molecular Mass Na3PO4)(moles of Na3PO4 in solution)

australopithecus · Answer

this will give you the moles of sodium in solution

Oh and if you didn't know

Molarity = Moles/Litres of total solution

australopithecus · Answer

1000mL = 1L

Thanks man, appreciate it! Had no idea where to even start.

australopithecus · Answer

yeah you can just use molecular mass ratios to solve these problems, if you were trying to figure out the total moles of the compound from the sodium ions you would just flip the ratio
