Answer:

Sustancia  Masa (g)  Composición (% m/m)

<em>Proteínas</em>      5,5                  4,4

<em>Azúcares</em>      5,0                  4,0

<em>Sodio            </em>0,06               0,048

<em>Potasio         </em>0,15                 0,12

                         

Explanation:

Para calcular la composición porcentual en masa de las sustancias debemos usar la siguiente ecuación:

\%_{m/m} = \frac{m_{s}}{m_{sol}} \times 100

En donde:

m_{s} es la masa de la sustancia

m_{sol} es la masa del yogurt = 125 g

Para las proteínas:

\%_{m/m} = \frac{m_{s}}{m_{sol}} \times 100 = \frac{5,5 g}{125 g} \times 100 = 4,4 \%

Para los azúcares:

\%_{m/m} = \frac{5,0 g}{125 g} \times 100 = 4,0 \%

Para el sodio:

\%_{m/m} = \frac{0,06 g}{125 g} \times 100 = 0,048 \%

Para el potasio:

\%_{m/m} = \frac{0,15 g}{125 g} \times 100 = 0,12 \%

Espero que te sea de utilidad!
