One is the reciprocal of the other. It is more common to use "mass per volume", but in theory you could use either. If object "A" has more mass per volume than object "B", then object "B" will have more volume per mass than object "A".
Since mass and volume are two different dimensional quantities, there is no meaning in saying that mass is greater or less than the volume.
The density of water is 1. Density is calculated by dividing mass by volume. For things that have density more than 1, they will sink in water. For things with density less than 1, they will float in water.
Body of water has large mass and volume. Rock has got less mass and volume. But still the rock sinks in the water. The reason is very simple. Density of the rock is more than water. Mass upon volume of the rock is more than water. So rock sinks in the water. That means rock is heavier than water, if the volume of both is same. Alternately the if you take the same mass of both, rock and water, volume of the rock is lesser than that of water.
If these measurements are made in cubic cemtimeters (volume) and grams (mass) this is true. But, if mass is from the english system, (not really pounds, it is slugs, but who knows what a slug is?) and the volume is cubic feet, this is not true.
Because volume is the ratio mass/density.
It makes no difference. Density = mass / volume. You divide the mass by the volume. If the volume is greater than the mass your answer will necessarilybe less than one, but that is still the correct answer showing the density in terms of the units used.

Any volume of non-vacuum anything has mass. Any mass has volume. Both mass and volume have an 'm' in the word. Other than that, they are not at all the same thing.
The mass is always less than the volume
Density is mass divided by volume. If we assume the mass of the iron and the cotton is the same, you will find that the iron will occupy less space (less volume) than that of the cotton. The value of a mass divided by a small volume is higher than the value of the same mass divided by a larger volume. If we assume the volume of both the iron and the cotton is the same, you will also find that the mass of the iron will be higher than the mass of the cotton. The value of a large mass divided by a volume is larger than the value of a small mass divided by the same volume. In both assumptions, the value of mass divided by volume for the iron is higher than the value of mass divided by volume for the cotton. Since density is mass divided by volume, the density of iron is therefore higher than the density of cotton.
The formula for mass if density is not given is mass=volume/power
No. Water ice for example will have a larger volume than an equal mass of liquid water.
No. An object's mass is not altered by its volume.
The density of an object is its mass divided by its volume. If that is less than the density of water, it will float; if greater it will sink
The density of water is 1. Density is calculated by dividing mass by volume. For things that have density more than 1, they will sink in water. For things with density less than 1, they will float in water.
