Bromine at standard temperature has diatomic molecules, and by definition one mole of anything has Avogadro's Number of molecules. Therefore, 2.6 moles of bromine contain 2(exact) X 2.6 X 6.022 X 1023 or 3.1 X 1024 atoms, to the justified number of significant digits.

The number of atoms of barium in 68.2 g of barium phosphate?
To find the number of atoms of barium in 68.2 g of barium phosphate, you first need to calculate the moles of barium in 68.2 g of barium phosphate using the molar mass of barium phosphate. Then, you can use Avogadro's number to convert moles of barium to atoms of barium.
How many atoms in iron?
26 protons 26 electrons and 30 neutrons
What is 850 mol Fe into atoms?
To convert 850 mol of Fe into atoms, we need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. 850 mol Fe x 6.022 x 10^23 atoms/mol = 5.12 x 10^26 atoms of Fe.
How many atoms are there in iron?
There are 26 atoms in one mole of iron, which corresponds to its atomic number on the periodic table.
How many carbon atoms does 2-hexyne have?
In Alkane with n C-atoms there are 2n+2 H-atoms, so if n=12 then number H's is (2*12)+(2) = 26
How many moles are represented by 4.70 x 1026 atoms of uranium?
To determine the number of moles, first calculate the number of moles in one mole of uranium using Avogadro's number (6.022 x 10^23 atoms/mol). Then, divide the given number of atoms by the number of atoms per mole to find that 4.70 x 10^26 atoms of uranium represents 7.81 moles.
How many atoms are there in 250 mol Si?
1 mole of anything is 6.022 x 1023 atoms or molecules of that substance. Thus, 2500 atoms of a substance is about 4.151 x 10-21 moles of that substance.
How many atoms are in 989 moles of manganese?
To find the number of atoms in 989 moles of manganese, you would use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Multiply this by the number of moles (989) to get the total number of atoms in 989 moles of manganese, which is approximately 5.95 x 10^26 atoms.
How many atoms are in 254.33 mol of O?
There are about 1.53 x 10^25 atoms in 254.33 mol of oxygen. This can be calculated by multiplying Avogadro's number (6.022 x 10^23 atoms/mol) by the number of moles.
How many argon atoms are contained in 7.66x105 mmol of argon?
To find the number of argon atoms, we first need to convert the amount from millimoles to moles by dividing by 1000. Next, we use Avogadro's number, which is 6.022 x 10^23 atoms/mol, to calculate the number of atoms in 7.66 x 10^2 moles of argon. The result is approximately 4.61 x 10^26 argon atoms.
The number of atoms of barium in 68.2 g of barium phosphate?
To find the number of atoms of barium in 68.2 g of barium phosphate, you first need to calculate the moles of barium in 68.2 g of barium phosphate using the molar mass of barium phosphate. Then, you can use Avogadro's number to convert moles of barium to atoms of barium.
What is the charge for a bromine ion with 26 electrons?
A bromine ion with only 26 electrons is not possible. A bromine atom has 35 electrons and it can't loose 9 electrons.
What is 850 mol Fe into atoms?
To convert 850 mol of Fe into atoms, we need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. 850 mol Fe x 6.022 x 10^23 atoms/mol = 5.12 x 10^26 atoms of Fe.
How many hydrogen atoms does dodecane have?
Dodecane has 24 hydrogen atoms. The general formula for an alkane is CnH2n+2, where n is the number of carbon atoms. Dodecane has 12 carbon atoms, so it will have 2(12) + 2 = 24 hydrogen atoms.
How many atoms in iron?
26 protons 26 electrons and 30 neutrons
How many atoms in all are in a molecule of serotonin?
A molecule of serotonin has 26 atoms in total.
How many moles of THC does this 26 ug represent?
To determine the number of moles of THC in 26 μg, we first need to calculate the molar mass of THC which is approximately 314.47 g/mol. Then, we divide the given mass (26 μg or 0.000026 g) by the molar mass to find the moles. This gives us approximately 8.3 x 10^-8 moles of THC.
