What is the mass of 5 moles of nitrogen?
Hence, Its molecular mass = 14 amu (7 protons and 7 neutrons.
How many grams are in 0.5 moles of nitrogen gas?
14 grams
What is the mass of 0.5 mole of oxygen gas?
That is, mass of one mole of a set molecules is gram molecular mass of that molecule. For example, molecular mass of a water molecule is 18 amu (2 amu for 2 hydrogen atoms, and 16 amu for one oxygen atom). So, mass of one mole of water would be 18 grams. Thus, mass of 0.5 moles of water would be 9 grams.
How many moles are in 20 grams of water?
1.11111
What is the mole of 22 gram of carbon dioxide?
0.5 mole
How many moles are in 25 grams of water show work?
1 Expert Answer Hydrogen has an atomic weight of 1; and oxygen has an atomic weight of 16 (check the periodic table for the atomic weights). So, one mole of water has a mass of 16 +1+1 = 18 grams. So, if one mole has a mass of 18 grams, 25 grams would have a mass of 25 grams/ 18 grams per mole or 1.39 moles.

What is Avogadro number constant?
Avogadro’s number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.× 1023. The units may be electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction (if any). See alsoAvogadro’s law.
How did Avogadro calculate the number?
The best estimate of the charge on an electron based on modern experiments is 1.x 10-19 coulombs per electron. If you divide the charge on a mole of electrons by the charge on a single electron you obtain a value of Avogadro’s number of 6.x 1023 particles per mole.
