Well there are many different ways to measure binary solutions. But when we are talking about particles then i would say ppm is the best measurement. You cannot measure particle in a volume rather use a specific measurement method like Moles in Volume. You can find all the ways to measure your solution you are trying to measure in Solutions page of wikipedia.

This corresponds to a value of 6×1023 of atoms of the substance in a given amount

What does a compound formula tell you?
A compound formula, or molecular formula, tells you about the chemical composition of the substance in terms of the number of atoms of that element that are present. From there, the empirical formula may also be derived by simplifying the molecular formula, as well as its structural formula.
How do you convert mass into weight?
First find the molar mass (or atomic mass) i.e h1206 would be (1*12)+(16*6). You then take that number and multiply it by Avrogondi's number which is: 6.02 *1023 which will then give you the # of representative particles in that mole.
What is mole percent?
Mole percent, or molar percent of a substance is the ratio of the moles of a substance in a mixture to the moles of the mixture. It represents the number of moles of a substance in a mixture as a percentage of the the total number of moles in the mixture. Mole % = (mol substance in a mixture) / (mol mixture) * 100
Grams to formula units?
It depends on the substance and its molar mass.In order to convert from grams to formula units, you must first convert grams to moles, then moles to formula units (grams --> moles --> formula units).1. Divide the mass (g) of the given substance by the substance's molar mass.2. Multiply the number of moles found in Step 1 (above) by Avogadro's number (6.022 x 1023).---- Mass substance ----- X 6.022 x 1023 formula unitsMolar mass substanceCONVERSION FACTORMass (g) substance x 1 mol substance ------- x ----- Avogadro's number/////////////////// molar mass (g) substance ------------ 1 mol substance
The fundamental density is the ratio of the mass of a substance to its volume this is known as what?
its density. note. density is often expressed as the ratio of the density of the substance to the density of water at standard temperature and pressure. This is known as the specific gravity of the substance. It is a dimensionless number so it has no units.
What is used to measure the number of representative particles in the substance?
mole
What is the SI unit used to measure the number of representative particles in a substance?
its the mole.
Which term is same for one mole of oxygen and water?
The number of particals (molecules, atoms, ions etc.) in one mole of ANY substance is the same: 6.022*1023 (Avogadro's number)
Shows the number and type of atoms present in the smallest representative unit of a substance?
chemical formula
Avogadros number of representative particals is equal to one?
Avogadro's number of any particles or countable objects, equals by definition 1 (exact) mole.
What does a pH level measure?
It measures the number of hydrogen ions in a substance.
What does a mole measure?
An instrument can not be used to measure moles because moles is the amount of grams of a substance divided by the molar mass of the substance. This can not be measured and has to be calculated.
How many atoms are in 2.8 moles o silicon?
One mole of any substance contains Avogadro's number of representative particles. Avogadro's number is 6.02x1023. So, if you have 2.8 moles of something, you multiply that number by Avogadro to get 1.69x1024.
Define one mole of a substance applied to atomic structure?
A mole is used to measure the amount of substance.1 mole of any substance contains 6.023 x 1023 molecules of that substance. 1 mole of a substance has mass equal to the atomic weight or molecular weight expressed in grams. Note:The number "6.023 x 1023" is called Avogadro's Number
Is 1 mole of particles a very large number of particles or a very small number?
1 mole of representative particles of a substance is a very large number. It represents 6.02294x1023 particles.
How many mgs are in 1.5ml?
It depends on the substance being measured. The milligrams (mg) in 1.5 milliliters (ml) will vary based on the density of the substance. To determine the exact number of mgs, you need to know the substance's specific gravity or concentration.
How many tablespoons of butter equal one eighth pound?
Tablespoon is a measure of volume, pound is a measure of weight. The number would differ depending on the density of the substance.
