AVOGADRO'S LAW: At the same temperature and pressure, equal volumes of all gases have the same number of molecules. At STP one mole of any gas occupies a volume of 22.4 L: this is the molar volume.

D. At STP (standard temperature and pressure), an ideal gas occupies 22.4 liters per mole. Here we have 48 g of oxygen gas or O2, each molecule of which consists of two atoms of the oxygen element. Since oxygen (O) has an atomic mass of 16 g, oxygen gas (O2) has a molecular mass of 2 x 16 = 32 g.

At STP 1 mole of an ideal gas = 22.4 liters. Assuming that water vapor behaves as an ideal gas, then... 0.08929 moles H2O x 6.02x1023 molecules/mol = 5.4x1022 molecules = 5x1022 molecules (1 sig. fig.)

The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*1023 * 55.556 = 3.346*1025 molecules. The number of atoms is 3 times larger because each molecule has three atoms, so there are 1.0038*1026 atoms in a liter of water.
