- Solvent
- component that is present in the solution in the greatest amount
- Solute
- component(s) that are present in the solution in the lesser amount
- Solutions
- homogeneous mixture (uniformed throughout)
- molarity(M)
- moles solute/liter solution
- percent by mass(mass percent)
- mass solute/mass solution x 100
- percent by bolume(volume percent)
- colume solute/volume solution x 100
- mass/volume percent
- mass solute(g)/volume solution(ml) x 100
- parts per million ppm
-
used for dilute solutions
mass solute(g)/mass solution(ml) x 10^6
mg/L=how you get ppm ration without 10^6 - parts per billion ppb
-
mass solute(g)/mass solution(ml) x 10^9
microgram/L=get it without 10^9 - parts per trillion ppt
-
mass solute(g)/mass solution(ml) x 10^12
ng/L=get it without 10^12 - molality(m)
-
moles solute/kg solvent
(not vary with temperature)
-only one with solvent on bottom other have solution - mole fraction
-
xnacl=molesnacl/total moles
total moles=moles of nacl+moles of h2o - mole percent
-
mole fraction x 100%=na/nt=pa/pt-must be gas to find partial pressure
Xnacl+XH2O=1.0 always
