Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
A kiloliter is a volume measure, and kilogram is a mass measure.
Volume = mass / Density Mass = Volume * Density Density = Mass / Volume
density = mass / volume Solving for mass: mass = density x volume Solving for volume: volume = mass / density
Density = mass/volume Mass = (density) x (volume) Volume = mass/density
scale measures force and/or mass; spoon measures volume
Percent per mass is exprimed in g/Kg, mg/kg, µg/kg, etc. Ex.: An ore contain 10 mg gold/kg ore. Percent per volume is exprimed in volume to volume. Ex.: Vodka contain 40 volumes of ethanol/100 volumes of liquid.
% of volume = 100*(volume of substance that you are interested in)/(total volume) % of mass = 100*(mass of substance that you are interested in)/(total mass).
The formula for percent by volume (% v/v) is: (Volume of solute / Volume of solution) x 100 The formula for percent by mass (% w/w) is: (Mass of solute / Mass of solution) x 100
Mass it how many particles an object has and volume is the space it takes up.
Percent by mass over volume is a measurement that expresses the mass of a substance in a given volume as a percentage. It is calculated by dividing the mass of the substance by the volume of the solution and then multiplying by 100. This measurement is commonly used in chemistry to quantify the concentration of a solute in a solution.
Percent per mass example: uranium concentration in granite is approh. 4 mg/kg. Percent per volume: uranium concentration in ocean water is approx. 4 micrograms/L.
To convert molarity to percent by volume, you would need to know the molar mass of the solute and the density of the solution. With these values, you can calculate the volume of the solute in a given volume of the solution to determine the percent by volume.
The difference in mass and volume percentages of iron in the Earth's crust is due to the fact that iron has a higher average density compared to the other components present in the crust. This results in a higher mass percentage of iron relative to its volume percentage. So, even though iron is only 0.49% by volume, its higher density contributes to it being 5.63% by mass in the crust.
mass is weight. volume accounts for size. density of items change therefore masses are not the same as volumes
Percent composition is usually expressed as a percent by mass, but in the case of gases and vapors, it is often expressed as a percent by volume.
It makes no difference. Density = mass / volume. You divide the mass by the volume. If the volume is greater than the mass your answer will necessarilybe less than one, but that is still the correct answer showing the density in terms of the units used.
Mole percent vs volume percent is a simple comparison to make. Mole percent is equivalent to moles of substance/moles of total x 100. Volume percent is volume of substance/volume of total x 100.
