If you suppose that the nail is pure iron, this material has atoms not molecules.
And the number of atoms in 3 g is 0,32535.10e23.
1.659 [grams] / 47.998 [grams / mol] * 6.02214179(30)×1023 [molecules / mole] * 3 [atoms / molecule]. A bunch.
3 moles of ammonia is 51grams. One mole is 17 grams.
Six 3x2=6 atoms, in 3 molecules of H2
2 g x ( 6.022 x 1023 molecules / 1 mole) x ( 1 mole / 79.9 g) x (3 atoms / molecule) = 4.522 x 1022 atoms
1.12875 × 1023
The mass of sodium is 22,91.10e-23 g.
1.659 [grams] / 47.998 [grams / mol] * 6.02214179(30)×1023 [molecules / mole] * 3 [atoms / molecule]. A bunch.
A mole of water is about 18 grams or 18 milliliters of water.A mole of water has 6.022 x 10^23 water molecules. And 10.0 grams of has 3.345 × 10^23 water molecules. And there are 3 total atoms in water molecules, which is H2O. (3.34 × 10^23)*3=1.006 × 10^24 Which means that 1x10^24 atoms are in 10.0 grams of water.
1 mole equals 6.022 x 10 to the 23 molecules
1.) Go to the store. 2.) Buy nail polish remover. 3.) Use as directed on the label.
The gram molecular mass of C2H4 is 28.05. Therefore, 1.26 X 103 grams constitutes (1.26/28.05) X 103 or about 44.9 moles. Each mole contains Avogadro's number of molecules; therefore, 1.26 X 103 grams contains 2.71 X 1025 molecules, to the justified number of significant digits.
3 pounds equals to 1360.77711 grams
