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.
% 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
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
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.
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.
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.
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.
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.
Your question doesn't have a single answer. In Chemistry solution strength is usually calculated in moles pe liter of mole per kilogram or as a mole fraction ( moles per mole) but can also be mass per liter, mass per mass, volume per volume, percent by mass, or percent by volume.
you have 40.0 ml of C6H5CH3.....that is put into 75.0 ml of C6H6,what is the percent volume of C6H5CH3?
Commonly used mass fraction units in chemistry include weight percent ( w/w), volume percent ( v/v), and mole fraction (X). Weight percent ( w/w) is calculated by dividing the mass of the solute by the total mass of the solution and multiplying by 100. Volume percent ( v/v) is calculated by dividing the volume of the solute by the total volume of the solution and multiplying by 100. Mole fraction (X) is calculated by dividing the moles of the solute by the total moles of the solution.
To calculate the percent mass/volume (m/v) of the solution, you would divide the mass of the solute (CaCl2) by the volume of the solution and then multiply by 100. In this case, the mass of CaCl2 is 60 g and the volume of the solution is 400 mL. So, the percent m/v would be (60g/400mL) x 100 = 15% m/v.
