33 Samsetning efna og lausna

Lykiljöfnur

% X = \frac{massi X}{massi efnasambands} \times 100 %

\frac{(sameindamassi eða mólmassi)}{(massi reynsluformúlu)} = \frac{n formúlueiningar}{sameind}

(A_xB_y)_n = A_nxB_ny

M = \frac{mól leysts efnis}{L lausnar}

C_{1} V_{1} = C_{2} V_{2}

massaprósenta = \frac{massi leysts efnis}{massi lausnar} \times 100 %

ppm = \frac{massi leysts efnis}{massi lausnar} \times 10^{6} ppm

ppb = \frac{massi leysts efnis}{massi lausnar} \times 10^{9} ppb
