Answer:

m_{soluto}=60g

Explanation:

¡Hola!

En este caso, al considerar la unidad de concentración de porcentaje masa/masa, podemos escribir su fórmula como:

\%m/m=\frac{m_{soluto}}{m_{solucion}}*100\%

Podemos identificar la masa de soluto (azúcar) como la incógnita, y resolverla como se muestra a continuación:

m_{soluto}=\frac{\%m/m*m_{solucion}}{100\%}\\\\m_{soluto}=\frac{20\%*300g}{100\%}\\\\m_{soluto}=60g

¡Saludos!

Identify whether the description refers to a monomer, a polymer, or both. Macromolecule:
larisa86 [58]

Answer:

Macromolecule: polymer

Repeating units: monomer

Simple molecule: monomer

Covalent bonds: both

Explanation:

A macromolecule is a very large molecule commonly created by the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more.

A  monomer is a molecule that can be reacted together with other monomer molecules to form a larger polymer chain.

Polymers include bounds between nonmetal atoms, therefore, they are joint by covalent bonds
