PbCl2 would not dissolve because it is insoluble based on the solubility rules for substances that will dissolve in water. This compound would instead form a solid precipitate at the bottom of the container.
At STP (standard temperature and pressure), one mole of a gas occupies 22.41 liters of volume. Avogadro's number (6.022*10^23) is the number of molecules per mole of a substance, or one mole of anything really. This means there are 6.022*10^23 molecules of any gas with a volume of 22.41 L at STP.
A (the first answer).
Explanation:
The mole is used because atoms are extremely small. If we found a way to count them by hand, the numbers would be in the millions. Great question!
