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.
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 concentration = (mass of solute/volume of solution) X 100 To solve for mass of solute, mass of solute = (percent concentration X volume of solution)/100 So, mass of solute = (10% X 100mL)/100 = 10g
Time squared over distance. No, it is not "Density". Density is mass divided by VOLUME. Weight is the force of gravity acting on the mass. force = mass * acceleration. Thus, mass/force = 1/acceleration, or, in generic units, time squared over distance. Don't believe every game show answer you hear.
mass of tooth over volume of tooth
% 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 of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
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.
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.
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.
It's always mass over volume, so you divide the mass by the volume then that is your density. mass/volume
by calculate density by dividind the mass of space
(mass /volume)x100
Density. This is quantified as a mass over a volume, so if you know the volume, the density will allow you to determine the mass of an object. Density equals mass divided by volume so mass is equal to density multiplied by volume.
mass over 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.
percent concentration = (mass of solute/volume of solution) X 100 To solve for mass of solute, mass of solute = (percent concentration X volume of solution)/100 So, mass of solute = (10% X 100mL)/100 = 10g
