1. What is the maximum amount of NaCl that can dissolve in
Sergio [31]

Answer:

70g

Explanation:

Rate = 35g of NaCl can dissolve in 100g of H2O

Use proportions for 200g of H2O:

\frac{35}{100} = \frac{x}{200}

Since 200 is double of 100, x needs to be double of 35.

\frac{35}{100} = \frac{70}{200}

Therefore the maximum amount of NaCl that can dissolve in 200g of water is 70g.

Dados los siguientes datos;

Tiempo = 50 segundos

Velocidad = 18.5 m/s

Para encontrar la distancia recorrida;

Matemáticamente, la distancia viene dada por la fórmula;

Distancia = velocidad * tiempo

Sustituyendo en la fórmula, tenemos;
