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 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.
Height and diameter will give you the volume, if you know the density you can then calculate weight from that.
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.
If the sample is homogeneous, then half of its volume has half of its mass and half of its weight.
Volume of a sample = (its mass) divided by (its density)
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
To determine the density of graphite, you need to measure the mass and volume of the graphite sample. You can then calculate the density by dividing the mass of the sample by its volume. The density of graphite is around 2.2 g/cm³.
To calculate the percent of air content in a soil sample, you need to determine the volume of air in the soil and divide it by the total volume of the sample. This can be done by measuring the bulk density of the soil and the particle density, then subtracting the particle density from the bulk density to get the volume of air. Finally, divide the volume of air by the total volume and multiply by 100 to get the percentage.
To calculate the volume of a pure zinc sample, use the formula: volume = mass / density. The density of zinc is approximately 7.14 g/cm³. Therefore, the volume of the 4.50 g sample of zinc is calculated as follows: volume = 4.50 g / 7.14 g/cm³ ≈ 0.630 cm³.
1. Apparent density: - weight a graduated cyllinder - put the sample in the graduated cyllinder up to a given volume (note this volume) - weight the graduated cyllinder with the sample - calculate the mass of the powder by difference - the density is the ratio mass of the sample/volume of the sample 2. True density of a powder: you need a helium pycnometer.
To find the volume of a sample of lead, you need to know its density. The density of lead is 11.34 grams per cubic centimeter. You can calculate the volume by dividing the mass of the lead sample by its density. In this case, the volume of a 17.6 gram sample of lead would be approximately 1.55 cubic centimeters.
To calculate the mass of the sample using dimensional analysis, you would use the expression: mass = volume × density Substitute the given values for volume (10.0 mL) and density (7.87 g/mL) into the expression to calculate the mass of the iron sample.
This depends on the nature and form of the sample:- for a solid with a regulate shape weight the sample and calculate the volume from the dimensions; density is the ratio between mass and volume. You can measure the volume of great sample by water displacement.- for other solids use a pycnometer- for liquids use a densimeter (simple or electronic)etc.
The density of a substance is calculated by dividing its mass by its volume. The formula for density is: Density = Mass / Volume. This calculation gives you a measure of how tightly packed the molecules are in a given sample of the substance.
Density is calculated by dividing the mass (in grams) of a substance by its volume (in milliliters or cubic centimeters). The formula for density is: Density = Mass / Volume. By measuring the mass of a sample in grams and the volume in milliliters, you can easily calculate the density of the substance.
Density of a substance = (mass of a sample of it)/(volume of the same sample)
