Explanation:
Hello!
In this case, since Helium is undergoing a volume-pressure change, according the Boyle's law, we infer the following equation is used:
Thus, since we are not given the volume at 0.25 atm, we can solve for V2 to do so:
Thus, we plug in to obtain:
Best regards!
The molality of the solution is 1.4 moles per kilogram (molal).
The molality of the solution is equal to the number of moles of sugar (solute) divided by the number of kilograms of water (solvent). Hence, the molality is determined below:
The molality of the solution is 1.4 moles per kilogram (molal).
