Answer 1

1. molalidad

m = moles de soluto
       ``````````````````````
           Kg solvente

2. Molaridad

M = mol soluto
       ````````````````
       v solución

3. Normalidad

N = equivalentes de soluto
       ``````````````````````````````
                v solución

4. Fracción molar (X)

Xsto = mol soluto
           ````````````````
           mol solución

Xste = mol solvente
           ```````````````````
             mol solución
