How many ATOMS are in a tank containing 10 moles of (gaseous) O2 molecules?
One mole of any substance contains Avogadro's number of particles, approximately (6.022 \times 10^{23}). Since each O2 molecule consists of 2 oxygen atoms, 10 moles of O2 would contain (10 \times 6.022 \times 10^{23} = 6.022 \times 10^{24}) O2 molecules. Therefore, the total number of oxygen atoms in the tank is (6.022 \times 10^{24} \times 2 = 1.2044 \times 10^{25}) atoms.
How many atoms are in 1.54 moles of Bromine Br?
If it is 1.54 moles of Br atoms then the answer is 9.274 X 1023 atoms.If it is 1.54 moles of Br2 molecules then the answer is 1.855 X 1024 atoms.
How much is 2 scientific moles?
Two moles is equivalent to 12,044281714.10e23 molecules, atoms or ions.
How many moles of hydrogen atoms does 5 moles of propane molecules contain?
Since propane has the formula C3H8, each mole of propane will have 8 moles of hydrogen atoms, so 5 moles of propane will contain 5x8=40 moles of hydrogen.

Results for Calculate The Amount In Moles Of Molecules For Each Substance. A) A Sample Of Ammonia NH3(g) Containing 8.1x1020 Atoms Of Hydrogen?
NH3 Molecules = ( 8.1 x 10^20 H atoms ) ( 1 NH3 molecule / 3 H atoms ) NH3 Molecules = 2.7 x 10^20 NH3 molecules NH3 moles = ( NH3 molecules ) / ( N Avogadro ) NH3 moles = ( 2.7 x 10^20 NH3 molecules ) / ( 6.022 x 10^23 molecules / mole ) NH3 moles = 4.48 x 10^-4 NH3 moles <--------------
How many moles of N2O molecules are present in a sample that contains 5.23 moles of nitrogen atoms?
Since each N2O molecule contains 2 nitrogen atoms, the number of moles of N2O molecules would be half of the moles of nitrogen atoms. Therefore, in this case, there would be 2.615 moles of N2O molecules present in the sample.

How many moles of NCl3 contain 2.55x1024 chlorine atoms?
To find the number of moles of NCl₃ containing 2.55 x 10²⁴ chlorine atoms, we first note that each molecule of NCl₃ contains 3 chlorine atoms. Therefore, the number of NCl₃ molecules can be calculated by dividing the number of chlorine atoms by 3: [ \frac{2.55 \times 10^{24}}{3} = 8.50 \times 10^{23} \text{ molecules of NCl}_3. ] Next, to convert molecules to moles, we use Avogadro's number (6.022 x 10²³ molecules/mol): [ \frac{8.50 \times 10^{23}}{6.022 \times 10^{23}} \approx 1.41 \text{ moles of NCl}_3. ] Thus, there are approximately 1.41 moles of NCl₃ in 2.55 x 10²⁴ chlorine atoms.
