Solubility, Molar conc., Molarity, Application of ideal gas equation.
3. The solubility of laughing gas, dinitrogen monoxide, in water is 7.50 mg per cent by mass at 760 Torr and 25C. If the density of the resulting solution is 1.01 grams per milliliter, what is the morality of the resulting solution? What is the % of the volume?

See the attachment.
Solubility = 7.5mg/92.5g H2O
= 7.5 x 10-3g/ 92.5 x 10-3g H2O
1g of H2O = 1ml H2O
1000ml H2O contains 7.5 x 10-3 x 1000 g/l
92.5 x 10-3
= 81.08g/l = Mass concentration
Molarity = mass concentration
Molar mass
Molar mass of N2O = ...
