i understand that you can see the moon during the day but why is it that i can see the moon at 12 PM and then see it rise over the ocean at 9:30 PM??

how can you see the moon in the day time and then see it rise at night?

The Moon is visible roughly 12.5 hours out of every 24 hours, with moonrise occurring about 50 minutes later every day. It's visible a little bit longer every day than everything else in the sky because it is always moving in orbit around the Earth.

if the Moon is Last Quarter, you will see it in the sky just after sunrise, then it will come up (Moonrise) about 6 hrs before Sunrise.

because it is not rising, it is setting. The other would be impossible.

It's possible to see the moon at noon (probably almost setting), and then see it rise at 9:30 PM.
We are all familiar with the fact that the length of sunlight varies during the year. For mid-northern latitudes, the sun is up for about 15 hours in June (and down for 9), and is up for about 9 hours in December (and down for 15).
If the moon is near setting at noon and rises at 9:30 PM, that means that it was down for about 9 hours. That is perfectly possible if both of the following conditions hold. (I'll assume that you're in the northern hemisphere.)
1) You're either at mid-northern latitudes or even farther north. (If you were at the equator, the moon would always be up for about 12 hours and down for 12 hours; so you could never see it rise and set at the times you described.)
2) The moon is at a very positive declination. (That means that for observers at the latitudes of the US or Europe, the moon will be above the horizon for more hours than it is below the horizon.)
Let me work on this for a few minutes and I'll come up with a concrete example.

OK, here's an example. Suppose you're at latitude 45N, longitude 75W (near Ottawa, Ontario, Canada), and look at the moon this summer on September 10. The moon will be just before last quarter. It will set that day at 1:18 PM EDT, and rise at 9:58 PM EDT. (This example works even better as you move east in the world on that day. You can find a place where it sets about 12:50 PM and rises about 9:30 PM, matching the times that you gave.)

Starting with the full moon - A day or two before the "full moon" you will see the
moon rise just before sunset. At full moon it will rise as the sun sets, and of course
after the sun sets as the time goes on. Each night after, notice how the light on the
moon shrinks from full to last quarter and then to nothing (a 2 week time period).
Also during this time you will notice the moon "traveling" closer to the sun.
Two weeks from full moon (day may vary) look for the sliver of the moon just before sunset.
As the moon moves into NEW moon and you cannot see at all, watch for it to become noticable
as a sliver in the other direction as the sun sets. Follow the light on the moon as
it expands to first quarter and then to full. So you can actually see the moon and the sun
at the same time virtually most of the month.
