What is the relationship between milliliters and cubic meters?

Answer 1

A mole is an arbitrary number of molecules in a single unit - refer to avogadro's number. Essentially, 1 mole is 6.022x10^23 molecules for ALL molecules or atoms, however one must remember that not all atoms/molecules are the same size, this is where mass comes into play. When you measure out 2 grams of carbon powder, there will be a lot more molecules present than if you weighed out 2 grams of thorium powder; this is because carbon is much smaller - kind of like a car filled with clowns, one given car can hold a lot of small clowns but only a few big ones; so the same volume is occupied but the amount of substance (clowns) varies on their own size. The arbitrary mass (relative to the hydrogen atom) for a molecule is the sum of its atomic components' atomic masses; e. g. C2H6's will have 2x12.00 (carbon) + 6x1.01 (hydrogen) = ~30 grams / mole.

Answer 2

1 M = 1000 mM, or 1000mM = 1 M

For example if any body wants to make a solution of 20 mM AgNO3 in 100mL solvent, than one need to find the amount of silver nitrate needed. So, the easiest step would be;

weight = strength x molecular weight of AgNO3 x V/1000

= 0.02M x 170 x 100/10000

= 0.34 g of AgNO3

Answer 3

use the density (g/ml) after that you should have no problem

Answer 4

at STP volume occupied by one mole of gas is 22.4dm^3...plus as we know mass=density*volume. so if we know the number of mols of a compound(liquid) and the density,we can determine the volume

Answer 5

Mole is accounted for 6.022×1023 particles, which can referred to amount of atoms or molecules.
