Answer:
the answer is in the picture
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.
Net ionic equation:
Be(2+) + 2OH(-) ----> Be(OH)2
