If an object is 3 times as dense as water with a mass of 5g with water what is the mass in air?

An object with a mass of 5 grams has a mass of 5 grams whether it's in water, air, ice, stone,
maple syrup, plasma, or scotch whiskey, and whether it's on earth, on the moon, inside Halley's
Comet, or out in space, and regardless of its density. Mass is mass, and at any speed much less
than the speed of light, mass doesn't change.

When should an object float into a liqud?
An object will float when it has less density than the fluid or substance that it is placed in. The object floats upward due to buoyant forces. Similarly, objects will sink if they are dense than the fluid.
How can you tell if a material is less dense then water?
Density is mass per unit volume, so if you know an object's mass and the space it occupies, then you can calculate its density. If you had a scale, you could weigh the object to determine its mass. (Note that mass is not the same as weight, but the two are closely related insofar as we use weight to determine mass.) You could then carefully submerge it completely in water to determine how much water it displaced. That would tell you its volume. You would then divide the mass by the volume to get its density. But what if you don't have a scale? Can you still determine its density? I think you can. Place a known quantity of water in a graduated container. Carefully place the object in the container and note the change in the water level. Subtract the new water level form the old. That is the amount of water displaced by the object, which should be floating since it's less dense than the water. The weight of the water displaced by the object is equal to the buoyant force pushing up on the object. What does this tell us? Well, since the object floats, we know that the buoyant force is equal (but opposite) to the weight of the object. In other words, if we know the magnitude of the buoyant force, we know the object's weight (and therefore its mass)! Now, you can divide its mass by its volume, which you determined earlier by fully submerging it. Determine how much water is displaced by the floating object. Then carefully fully submerge the object and record how much water is displaced. If you divide the first number by the second, you will know its relative density compared to the density of water! If the floating object displaces 100 ml of water and the fully submerged object displaces 150 ml, then the relative density is 100/150 = 0.667. Since the density of water is 1.00 g/cm3, that means the density of the object is 0.667 g/cm3.
The mass of an object in kilograms times its velocity is?
The mass of a object in kilograms times its velocity is its momentum.
What is created when a mass of more dense water sinks beneath less dense water?
a big wave
Why does mercury have a higher density than water?
Mercury is a metal that is liquid at room temperature. Metals are generally heavy, dense, closely packed materials. The molecular mass of water (H2O) is (2x1) + 16 makes 18. The molecular mass of mercury is about 201. Mercury is about 11 times as dense as water.
How can you predict if something will sink or float?
An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away. The Greek mathematician Archimedes discovered that the amount of water displaced by an object depends on the mass of that object. Mass is the amount of matter in a substance, and dense objects have more mass than less dense objects. Dense objects that do not displace much water will sink, while less dense objects that displace a lot of water will float.
How can you predict whether an object will sink or float?
The density of water is 1 g/cm cubed, and objects more dense that water will sink, while objects less dense than water will float. An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away. The Greek mathematician Archimedes discovered that the amount of water displaced by an object depends on the mass of that object. Mass is the amount of matter in a substance, and dense objects have more mass than less dense objects. Dense objects that do not displace much water will sink, while less dense objects that displace a lot of water will float.

How does an object's density determine whether the object will sink or float in water?
the simple rule is that if your density is higher than the substance it will sink and if it is lower it will float density= mass divided by volume. Example:Mass 7.5g Volume:2cm3 so 7.5 Divided by 2= 3.75g/cm3 that is your density of object
Why does something sink or float according to buoyancy?
Density (mass x volume) of the object. If the object is less dense (helium in air, or foam in water) than the fluid in which it is placed, it will float. Likewise, if the object is more dense (lead in water, or water in air), it will sink.
How do the least dense particles move to the bottom of a liquid?
This question is misguided. Density is a property which pertains to the entire substance, not to particles. It is the mass per unit volume. In general it is more dense substances which sink. Thus grains of sand will sink in water. In order to float, an object has to displace a volume of water whose mass is the same as the object. If the object is more dense than water, by definition it cannot do this, so it sinks.
What is the desnity of an object that has a mass 350 g and a volume of 95 cm's 3 Would this object float in water Explain?
It would sink because the object is more dense than the water.
Is a coin more dense than water?
The formula for density is mass divided by volume. If the mass of something increases, the volume will increase by the same degree, so no, a coin (or any object) will not differ in density because it has a larger mass.

Will kilogram float in water why?
The mass of an object alone is not enough to determine whether it will float in water. You need to know the object's mass and its volume; in other words, its density. A kilogram of solid lead will sink in water. A kilogram of styrofoam will float. If an object is less dense than water it will float; if it is denser it will sink.
How is the density affected by increasing the mass?
if you increase the mass of an object density is affected because now the object is MORE dense.
