I'm not sure if you mean 'mols' of a compound. If you do, divided the total mass of the compound, by the Mr (relative atomic mass). When working out the Mr, use the Periodic Table and use the top number above the element. Ignore the ratio numbers infront of the compound, for example 2H20, only use that for your molar ratio
The allowable concentration level of vinyl chloride, C2H3Cl, in the atmosphere in a chemical plant is 6.52e-6 g/L. How many molecules per liter is this?
One mole of anything has 6.02x10^23 atoms or molecules.
Solubility is determined experimentally.
By amount I assume you mean moles. The amount of moles per liter and the amount of moles are the same if you calculate from 1 L (which is what you do when you have, for example, 0,30 M) 0,30 M = 0,30 mol/liter, if you have 1 liter that means you have 0,30 moles. So you can use either moles or mol/liter.
The same way as you would with anything else. It is merely mg per liter.
12km per liter equates to 6km per 500mL
The answer is 9,3945.1023 molecules.
Use this formula: mpg x 0.425 = km per liter
The lower the temperature, the more close the molecules will be. Therefore the will be less molecules in ice than in water. So water will have more molecules per litre.
Solubility is determined experimentally.
liter
Multiply the number of molecules by the number of molecules per mole for that particular element or molecule (sum of the molecules/mole of each element in the molecule). The number of molecules per mole for any element can be found on charts and on the periodic table.
To convert miles per gallon to km/L use this formula - mpg x 0.425 = km/L
129 (grams per liter) = 129,000,000 micrograms per liter.
In order to convert a microliter per liter to a mililiter per liter, just divide by 1,000.
1 mg = 1,000 ug 1 mg per Liter = 1,000 ug per Liter. 1 mg per Liter is 1,000 times as concentrated as 1 ug per Liter.
You cannot. The problem here is you have weight per area and you want to convert to weight per volume. You need a third dimension to the area to calculate this.
The answer depends on the strength of the beer.
