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.
To calculate the mass of water, you can multiply the density of water (1 g/cm3 or 1000 kg/m3) by the volume of water. The formula is: mass = density x volume. For example, if you have 1 liter of water, the mass would be 1000 grams.
To calculate the volume of water (H2O) needed for a specific experiment, you can use the formula: Volume Mass / Density. First, determine the mass of water required for the experiment. Then, find the density of water, which is approximately 1 gram per milliliter. Divide the mass by the density to calculate the volume of water needed.
You can calculate the mass of an object by multiplying its density by its volume. The formula to calculate mass is: mass = density x volume.
To calculate the density of an ethanol-water mixture, you would use the formula: Density (mass of ethanol mass of water) / (volume of ethanol volume of water) You would need to know the masses and volumes of both ethanol and water in the mixture. Then, you can plug these values into the formula to find the density of the mixture.
To calculate the density of borated water, you can use the formula: density = mass / volume. First, measure the mass of the borated water using a scale. Then, measure the volume of the borated water using a graduated cylinder. Divide the mass by the volume to determine the density of the borated water.
You would need to know the density of the object in order to calculate the volume from the mass. The formula to calculate volume from mass and density is: Volume = Mass / Density.
density = mass/volume
Calculate the density (mass divided by volume) of your object. If the density is less than that of water - which has a density of about 1000 kg per cubic meter - then it will float; if the density of your object is more, it will sink.
To calculate volume based on density and mass, you can use the formula: Volume = Mass / Density Rearrange the formula to calculate volume by multiplying mass with reciprocal of density: Volume = Mass * (1 / Density)
Density = Mass/Volume so Mass = Density*Volume.
mass= density*volume
To find the density of water at a specific temperature, you can use a reference table or formula that provides the density of water at different temperatures. Alternatively, you can measure the mass and volume of a sample of water at that temperature and use the formula density mass/volume to calculate the density.
