To find the solubility of the salt in grams per 100 grams of water (g salt/100g H2O), we need to determine the amount of salt dissolved in the given amount of water.
The solubility can be calculated using the following formula:
Solubility = (Amount of salt dissolved / Amount of water) x 100
In this case, we know that 3.2 grams of the salt is dissolved in 9.10 grams of water. We substitute these values into the formula:
Solubility = (3.2 g / 9.10 g) x 100
Calculating the division:
Solubility = 0.35164835 x 100
Solubility = 35.16 g salt/100g H2O
Therefore, the solubility of the salt is 35.16 grams of salt per 100 grams of water.
