Answer:
~0.0004
Explanation:
n=0.072/(56+(35.5*3))=0.072/162.5~~0.004
Answer : The number of moles of gas are in container 2 are 12.008 moles.
Explanation :
According to the Avogadro's Law, the volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.
or,
where,
= initial volume of gas in container 1 = 1.30 L
= final volume of gas in container 1 = 2.33 L
= initial moles of gas in container 2 = 6.70 mole
= final moles of gas in container 2 = ?
Now put all the given values in the above formula, we get the final moles of the gas.
Therefore, the number of moles of gas are in container 2 are 12.008 moles.
Answer:
The solubility of gases depends on the pressure: an increase in pressure increases solubility, whereas a decrease in pressure decreases solubility. This statement is basically Henry's Law, which states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution. This can be expressed in the equation:
s=k×Pgas
where s is solubility in M
k is Henry's constant in M/atm
P is the vapor pressure of the gas over the solution
Another way of explaining this is that higher pressures lead to greater force in collisions between the gas particles above the solution and the solution itself. Their average kinetic energy is greater, and their average speeds are greater. So it is more likely that some of the particles will go into the solution and get dissolved.
