Answer:
636 balloons
Explanation:
If we assume that helium gas follows an ideal gas behaviour, we can use the ideal gas law to solve this problem as follows:
- We consider two different states, the initial given by the conditions of the problem statement and the final, when the tank reaches atmospheric pressure and it's no longer able to fill balloons:
- To find out what would be this volume 2, we use the Boyle's Law:
- Now we find the available volume to fill the balloons by substracting both, volume 2 and volume 1:
- Finally, we determine the quantity of ballons by dividing that available volume between the volume of each ballon:
Answer:
a. Molarity=
b. Molality=
Explanation:
Hello,
In this case, given the information about the aniline, whose molar mass is 93g/mol, one could assume the volume of the solution is just 200 mL (0.200 L) as no volume change is observed when mixing, therefore, the molarity results:
Moreover, the molality:
