Question

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.) *

Answer 1

70g

Step-by-step explanation:

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

Use proportions for 200g of H2O:

`(35)/(100) = (x)/(200)`

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

`(35)/(100) = (70)/(200)`

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