Answer:
V = 11.2 L
Explanation:
Hello there!
In this case, according to the ideal gas equation:

It is possible to compute the volume as shown below:

Whereas the moles are computed are computed given the mass and molar mass of oxygen:

Now, since the STP stands for a temperature of 273.15 K and a pressure of 1 atm, the resulting volume is:

Best regards!
So the acceleration has actually slowed down the ball because it was going in the direction opposite the velocity. Now see what happens as the ball falls back down to Earth. The ball has zero velocity, but the acceleration due to gravity accelerates the ball downward at a rate of –9.8 m/s2.
hope it helps
When one observes the phase of matter of water, one observes a physical property of matter.
