Originally Answered: How many O atoms are in 3.0 moles of CO2 ? A mole is 6.022 times 10 to the 23rd power. There are two atoms of oxygen in every carbon dioxide molecule, and there are 3 moles of carbon dioxide; therefore there are 3.6132 times 10 to the 24th power atoms of oxygen in 3 moles of pure carbon dioxide.

1 mole of Mg3(PO4)2 (molecule) contains 3 moles of Mg atoms, 2 moles of P atoms and 2X4 moles of O atoms. = 0.03125 moles.

A The empirical formula—Ca3(PO4)2—indicates that the simplest electrically neutral unit of calcium phosphate contains three Ca2+ ions and two PO43− ions. The formula mass of this molecular unit is calculated by adding together the atomic masses of three calcium atoms, two phosphorus atoms, and eight oxygen atoms.

The correct answer to this question is D; the empirical formula for a compound that is 43.6% phosphorus and 56.4% oxygen is P2O5. In the formula, the P stands for phosphorus and the O standards for oxygen, so there are 2 phosphorus (P) atoms and 5 oxygen (O) atoms in the compound.

One mole of P4 has a mass of 123.90 grams and one mole of P4 has 6.02 x 10^23 molecules. The number of phosphorus atoms in one mole of molecules is 4 * 6.02 x 10 ^23 atoms.

The molecular mass of O3 is 3 times the atomic mass of Oxygen atom. 16 g O3 means 1/3 moles of it. As one molecule of O3 have 3 atoms . 16 g of O3 will contain one mole of Oxygen atoms.
