You have to know two out of three ... mass, volume, density ... then you can find the missing one.
If density is missing . . . Density = (mass)/(volume)
If mass is missing . . . Mass = (density) x (volume)
If volume is missing . . . Volume = (mass)/(density)
density = mass/volumemass = density*volumevolume= mass/density
Any substance with a density of 2.7 grams per cm3. Aluminium and Al alloys have a density of around 2.7 gcm-3
Converting a percentage to liters is not a straightforward formula as percent is a measure of a part per hundred while liters are a unit of volume. To convert a percentage to liters, you would need to know the density of the substance in question. The formula would involve multiplying the volume of the substance by its density to determine the amount in liters.
The one which has a density of 2.5 g/ml (making its volume 8 ml).
To find density, you must use the formula of D=M/V or density = mass divided by volume. You have given us 9g as a volume, but that should be either liters or some other measurement of volume. I'll assume liters. 45/9 = 5. So, The density of a solid that has a mass of 45 grams and a volume of 9.0 liters would be 5 grams/liter.
The density of the sample is calculated by dividing the mass (77.0 g) by the volume (36 mL). The density of the sample would be 2.14 g/mL.
Based on the formula Desnity= Mass/Volume. The answer would be 13.5 g/cm3
Its density. Density is mass per unit volume.
density = mass / volume Solving for mass: mass = density x volume Solving for volume: volume = mass / density
density = mass / volume
If the amount of sample increased while the volume remained the same, the density would increase since the mass would be higher with the same volume. Density is calculated as mass divided by volume, so an increase in mass while keeping volume constant would result in higher density.
The formula for density is density = mass/volume. Density is a measure of mass per unit volume, so you would divide the mass of the object by its volume to find its density.
The density of copper can be calculated using the formula: density = mass/volume. In this case, the density of copper would be 267g/30cm^3 = 8.9 g/cm^3.
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.
The volume of a sample of galena with a mass of 300 g would depend on its density. The density of galena is approximately 7.5 g/cm^3. Using the formula Volume = Mass/Density, the volume can be calculated as 300 g / 7.5 g/cm^3 = 40 cm^3.
The identity of the sample can be determined by calculating its density, which is mass divided by volume. In this case, the density would be approximately 7.18 g/cm³. By comparing this density to known values for different substances, you can identify the sample based on its density.
Divide the number of grams by the density (the density of lead is about 11 grams/cubic centimeter - look it up if you need more precision). If the density is in grams/cubic centimeter, the answer is the volume in cubic centimeters.
