How many moles of carbon atoms can be obtained from the decomposition of C6H6 in a 1.68 moles sample?
10.08 moles (there are six carbon atoms per molecule of C6H6, hence, six times the number of moles of carbon can be produced).
How many moles are present in a sample of 3.2x10 atoms of nickel?
A sample of 3,2x10 atoms of nickel is equal to 0,53.10e-23 moles.
Does two moles of O3 contain the same number of oxygen atoms as three moles of O2?
Yes, 2 times 3 atoms in 2O3 = 6 atoms = 3 times 2 atoms in 3O2
How many moles of Mg is 2.01 times 10x22 atoms?
2.01x10^22 atoms x 1 mole/6.02x10^23 atoms = 0.0334 moles
How many moles is 2.80 times 10 to the twenty third power atoms of silicon?
The answer is 0,465 moles.

Aluminum will react with bromine to form aluminum bromide Al2Br6 What mass of bromine g is needed to form 1.42 mol of Al2Br6?
The gram formula unit or molar mass for aluminum bromide is 533.38.* Therefore, 1.42 moles has a mass of 757.4 grams. The mass of 6 moles of bromine atoms is 479.42. Therefore, the mass fraction of bromine in aluminum bromide is 479.42/757.4 or 0.633, and the mass in grams of bromine required to form 1.42 moles of aluminum bromide is 0.633 X 757.4 or 479 grams, to the justified number of significant digits (limited by the precision given for the number of moles.) ___________________ *This is equal to the sum of (2 times the gram atomic mass of aluminum) and (6 times the gram atomic mass of bromine).
Does two moles of O3 contain the same number of oxygen atoms as three moles of O2?
Yes, 2 times 3 atoms in 2O3 = 6 atoms = 3 times 2 atoms in 3O2
How many moles of Mg is 2.01 times 10x22 atoms?
2.01x10^22 atoms x 1 mole/6.02x10^23 atoms = 0.0334 moles

The number of moles is 0,528.
How many moles are in 1.51 times 1015 atoms?
1.51 X 1015 atoms (1 mole/6.022 X 1023) = 2.51 X 10 -9 moles ===============
How many moles of silicon do you have if you have 6.02 x 1024 atoms?
A mole of the element silicon is generally considered to have Avogadro's Number of atoms, since there is no particular small number of silicon atoms that is known to have distinct and persisting chemical bonds different from those of any other part of a sample of silicon. The number shown in the question is about 10 times Avogadro's Number and therefore contains ten moles.
