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 volume of toluene at room temperature is 31.84%.
The gas with a percent volume of 78.09 is nitrogen (N2).
No, mole percent and volume percent are not necessarily equal for a gas. Mole percent is the ratio of the moles of a gas to the total moles of all gases in a mixture, while volume percent is the ratio of the volume of a gas to the total volume of all gases in a mixture. The two can be equal only if the gases have the same molar volume at the given conditions.
% 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).
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.
if this is math and your asking what gas has a percent by volume 78.09 it is nitrogen
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
Oxygen makes up 21 percent of the air by volume.
9,200,000 is the total volume.
The percent volume of ethanol in a solution is the volume of ethanol divided by the total volume of the solution, multiplied by 100. It is commonly used to express the concentration of ethanol in alcoholic beverages or solutions.
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.
