You have to use the density equation...
D = M / V
D= density
M= mass
V= volume
You have to find the volume of your water. Since you know your density the only thing left to find out is the mass. Just solve for it by multiplying the volume times the density.
density= mass/volume 30g/7500cm3=.004g/cm3
if you want to calculate mass with volume density it is easy. there is this thing called the magic triangle. it goes mass over volume beside density mass=volume x density volume= mass/density density= mass/volume if you get that it is simple
You need to know density and percent by weight. Then use the following formula: ((1000)density x % by weight) / formula mass=concentration
Compare its weight to the weight of an equal volume of water. The weight of the specimen divided by the weight of the water equals the density of the specimen.
Density is measured by mass per volume and the expressed formula is P=M/V where P represents Density, M represents Mass and V represents Volume. Specific density is a measurement of density relative to another substance and the expressed formula is Substance=P substance/ P reference. An example of specific density is measuring salt in ocean water and comparing it to salt in fresh water.
You know that the density of pure water is 1g/cm3. If you also know the volume of the water, you can multiply the two and get the mass.
density = mass/volume
Density = Mass/Volume so Mass = Density*Volume.
mass= density*volume
density = mass/volume If you know density and mass, you can calculate the volume by manipulating the density equation such that volume = mass/density. Example: density = 3.57g/cm3 mass = 2.4g volume = ? volume = mass/density = 2.4g/3.57g/cm3 = 0.67cm3
by calculate density by dividind the mass of space
The steel has a density greater than water; but the ship does not. To calculate density, you divide mass by volume. This includes the mass - and the volume - of any air trapped inside the ship.
The shape of an object is not enough to calculate its density. You also need its mass and then Density = Mass/Volume.
density = mass/volume mass = density x volume
density=mass/volume volume=mass/density
density = mass/volumemass = density*volumevolume= mass/density
Density is the mass of a substance divided by the volume of that same mass of substance.
