2 (atoms N / molecule N2) * 8.5*10+24 (molecules N2) / 6.02*10+23 (atoms N / mole N-atoms) = 28 mole N-atoms
A total of 8.37*1023 molecules of N2 are in (8.37*1023) / (6.022*1023) = 1.39 moles
1 mole of gas occupies 22.4 litres at Standard Temperature and pressure. Assuming this is the case then there is 8.96/22.4 =0.4 moles.
By the definition of Avogadro's Number, each mole contains 6.022 X 1023 molecules. Therefore, (9.25 X 1024)/(6.022 X 1023) or 15.4 moles are required, to the justified number of significant digits.
Four moles of sulfur dioxide would consist of how many molecules?
There are 9 moles of NH4 (Ammonium ions) in Ammonium carbonate. There are 2 moles of NH4 per molecule and 4.5 molecules, so 2 moles times 4.5 is 9 moles.
10 moles of oxygen atoms or 5 moles of oxygen molecules.
1 mole=6.02*1023 molecules or atoms5.23 moles=6.02*1023 * 5.23= {[(3.14846*1024molecules)]}
.565 MOLES
3.01 x 10 to the 23 power of molecules
The answer is 0,465 moles.
4.651024 molecules of NO2 equals 7,721 moles.
23 moles of oxygen contain 138,509.10e23 molecules.
24 times Avogadro's number (6.022 x 10 to the 23).
0,565 moles
20.1 moles
6.32 mol carbon dioxide
1,125 moles of sodium sulfate contain 6,774908464125.10e23 molecules.
By the definition of Avogadro's Number, each mole contains 6.022 X 1023 molecules. Therefore, (9.25 X 1024)/(6.022 X 1023) or 15.4 moles are required, to the justified number of significant digits.
3.75 X 1024 molecules carbon dioxide (1 mole CO2/6.022 X 1023) = 6.23 moles carbon dioxide ==================
