x = 30(100)/1 = 3000 cm
Answer:
Basically, solubility increases with temperature. It is the case for most of the solvents. The situation is though different for gases. With increase of the temperature they became less soluble in each other and in water, but more soluble in organic solvents.
Answer:
About 7.9 L.
Explanation:
We can utilize the ideal gas law. Recall that:

Because the amount of carbon dioxide does not change, we can rearrange to formula to:

Because the right-hand side stays constant, we have that:

Hence substitute initial values and known final values:

Therefore, the final volume is about 7.9 L.
