N yogurt de 125 g muestra en su etiqueta el contenido de algunas de sus sustancias nutricionales:¿Cuál es la composición en tant
poizon [28]

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 \%

The examination of a microscopic slice of an object with a petrological microscope in order to determine the source of the mater
zvonat [6]

The examination of a microscopic slice of an object with a petrological microscope in order to determine the source of the material, is known as thin-section analysis.

<h3>What is thin section analysis?</h3>

The microscopic analysis of the content and structure of sediments is known as micromorphology, often known as thin-section analysis. Concepts of plasmic fabric and morphological traits and structures, which date from the early 1960s, were initially established in soil science.

<h3>What makes petrography significant?</h3>

An essential tool for the fluid inclusion study is petrography. The fundamental purpose of petrography is to classify the fluid phases, such as monophase, biphase, or multiphase, and to deduce the relative chronology of the entrapment of fluid inclusions to determine whether it is primary, secondary, or pseudosecondary.
