There is no single standard here; sometimes, percentages are used (either volume or mass percentages; the numbers may be different for the same mixture, due to different densities); mass per volume (e.g., grams per liter); or moles per volume (e.g., moles per liter).
You haven't given the volume of solution. M means moles per liter. First off you divide 5 by 1000 and multiply by the amount of mls you have to find out how many moles that you have. then multiply by molecular weight of NaCl
molarity is the number of moles dissolved per volume of a solution in dm cube molarity=mass of solute in gram __________________ 1 * _________________ molecular mass of solute volume of solution in dm cube OR molarity=no.of moles ________________ volume of solution in dm cube
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).
Use general gas law: V = n.R.T / pin which:n = number of moles (to be filled in)R = gas constant = 8.20*10-2 (L.atm.K-1.mol-1)T = tempeature (K) = 273 K (stand.T)p = pressure (atm) = 1.00 atm (stand.P)then the calculated volume is in Liter
