1. What is the maximum amount of NaCl that can dissolve in
200 g of water? (The solubility of NaCl is 35 g/100 g H20 at
20°C.) *

Respuesta :

Answer:

70g

Explanation:

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

Use proportions for 200g of H2O:

[tex]\frac{35}{100} = \frac{x}{200}[/tex]

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

[tex]\frac{35}{100} = \frac{70}{200}[/tex]

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