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.) *

70g

Explanation:

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

Use proportions for 200g of H2O:

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

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