When soda companies add carbon dioxide gas to a soda mixture, the water is very cold so it can hold a lot of gas. They also use pressure to put more gas in the water than it could normally hold at that temperature.
But when a soda can warms up a bit or when the can is shaken, that extra gas is really ready to come out. So when you open up the can and release the pressure, splooosh!
The correct answer is A. The statement is true. Boiling happens when the pressure in a liquid sample is equal to the pressure of its surroundings or the atmospheric pressure. For this problem, we are given the pressure of the system as 745 mmHg which is clearly not equal to the atmospheric pressure of 761 mmHg therefore boiling cannot happen.
Molality= moles/ Kg of solvent
You need to change the grams to moles. Since you did not say what the solute is, I can't change the grams to moles.
