Molecular Mass

1 mole of any element contain 6,022 140 857.1023 atoms (Avogadro number).
2,5 moles of magnesium contain 15,0553521425.1023.

1 mol = 6,022 140 857(79).10e23 atoms.
0,25 mol is 1,50553521425.10e23 atoms.

550 g of nitrogen dioxide is equal to 11,94 moles.

1 mole of iron atoms has the greatest mass - 55,845 g.

0,092 moles CaO

8,23.1023 atoms Mg is equivalent to 1,366 moles.

3 moles of (ClO4)3- and 1 mol Al
Aluminium perchlorate is Al)CLO4)3.10H2O.

16,8 L of Xe gas at STP is equivalent to 0,754 moles.

To find the number of moles in 573.28 g of AgCl, you need to divide the given mass by the molar mass of AgCl. The molar mass of AgCl is approximately 143.32 g/mol. So, 573.28 g / 143.32 g/mol = approximately 4 moles of AgCl.

The reaction is 2HCl(aq) + Mg(s) ==> MgCl2(aq) + H2(g)
3.143 moles HCl will yield 1/2 x 3.143 moles of H2 gas (see balanced equation stoichiometry)
Thus, 3.143 moles/2 = 1.5715 moles H2 gas will be produced
At STP 1 mole - 22.4 liters, thus 1.5715 moles x 22.4 L/mole = 35.20 liters of H2 gas formed

4,96 x 1024 molecules of glucose is equal to 8,236 moles.

A 63,60 g sample of carbon is equal to 5,296 moles.

53,2 g of palladium contain 0,5 moles.

3 moles in 1 liter = 3 M

Mass of ammonia is 17. Mass of Hydrogen in it is 3. So the percentage of hydrogen by mass is 17.64%

In liquids, molecules are close together while in gases, molecules are very far apart. As liquids are heated, temperature increases and the energy in the molecules increase. The molecular motion becomes so great that the intermolecular forces between molecules are interrupted. In other words, the molecules move so fast that they break free from the liquid and form a gas.

Polarity affects boiling temperature. The greater the intermolecular forces are, the higher the boiling temperature is because it takes more energy to overcome the intermolecular forces. Hydrogen bonding is a particularly strong type of intermolecular force. For example, water, which has hydrogen bonding, therefore needs a high temperature before the energy in the moving molecules are enough to overcome the strong hydrogen bonds. Molecules with hydrogen bonding have higher boiling temperatures than nonpolar molecules with weak London Dispersion Forces.
