Yes, gravity exists near anything that has mass. If you remove the air from a container, what's inside won't float.

well at first glance yes, gravity is created by gravitons from things that have mass e.g F=-G(m1Xm2/r^2) but if in a vacuum there is nothing then it has no effect on anything, However if a vacuum is empty e.g does not have mass in it, then there is nothing that gravity can have an effect on... rite but massive objects distort space, therefore gravty does have an effect on what we measure as a vacuum (space) so yes there is gravity in a vacuum, and we can only measure gravity by using something that has a mass therefore we are no longer measuring a vacuum. sooo in summary something in a vacuum will experiance a gravitational pull however that something means that it is not a vacuum. but as we know that massive objects with gravity distorts space then then there is gravity in space.

Yes, gravity exists everywhere because gravity is caused by matter (the greater the mass of the matter, the greater its gravitational attraction). 'Vacuum' can be ambigous, because it means the absence of matter. If you mean vacuum as in outer space, the answer is still yes. But if you take 'vacuum''s literal meaning then there can exist no gravity because for gravity to exist, matter is required.

gravity can be found anywhere where a mass is present and vacuum is created in the absence of a gaseous medium . so basically the two are not related and in general if a solid or a liquid exists in a vacuum gravity exists otherwise it doesn't.

No.
Gravity is the attraction of two bodies. If there is a true vacuum, there are no particles in the vacuum. Therefore, no gravitational pull.
However, if there is a test particle in the vacuum, it will be affected by gravity.

If there was no gravity in a vacuum then you would not be able to stand on the moon, which has no atmosphere. The hammer and feather would just float, as would the astronauts.

Gravity is a result of a mass, whether or not the mass existed in vacuum or non-vacuum.

Gravity is actually the curvature of space and time. Space and time bends if there is any mass inside it. So if there is nothing in the vacuum - no bending of space-time so no gravity. Whenever there is any mass in the vacuum - the space-time will bend around it - so there will be gravity.

Since gravity is the curve in space time, it is not affected if there is a vaccuum. There can be gravity in a vaccuum. There is vaccuum between the sun and the earth, then also the sun's gravity affects us. But there must be mass in vaccuum. If you mean to say that there is complete vaccuum with nothing in it, no even stars, planets or other matter, then there will be no gravity.

yes
thats how we sent people to the moon and got them back. thats what keeps sattelites in orbit. a vacuum is the absence of air (or other fluid material).
space is a vacuum. thats how this entire solar system and galaxy and universe is holding together. we have gravity in a vacuum holding us all relative to each other
