How many molecules of bromine are present in 120 grams of bromine gas?
To determine the number of molecules in 120 grams of bromine gas, you first need to calculate the moles of bromine using its molar mass (molar mass of Br2 = 159.808 g/mol). Then, use Avogadro's number (6.022 x 10^23) to find the number of molecules in that many moles of bromine gas.
How many atoms of bromine will you multiply to get moles of bromine?
To convert atoms of bromine to moles of bromine, you would need to divide the number of atoms by Avogadro's number (6.022 x 10^23). So, to get moles of bromine, you would divide the number of atoms by Avogadro's number, not multiply.
How many moles of bromine are in 2.60100 grams of bromine?
To determine the number of moles in 2.60100 grams of bromine, we first need to calculate the molar mass of bromine, which is 79.904 g/mol. Then, we use the formula: moles = mass / molar mass. Substituting the values, we get moles = 2.60100 g / 79.904 g/mol = 0.03255 moles of bromine.
How many molecules are in 3.01 moles of bromine?
There are approximately 1.81 x 10^24 molecules in 3.01 moles of bromine. This can be calculated using Avogadro's number, which is 6.022 x 10^23 molecules/mol. Multiply this by the number of moles to get the number of molecules.
How many moles of bromine atoms in 1 mole of bromine gas Please show equation?
1 mole of bromine gas (Br2) contains 2 moles of bromine atoms. This can be shown by the balanced chemical equation: Br2 (g) -> 2Br (g)
How many moles of Br2 are there in 160g?

How many molecules would be in two moles of bromine gas (Br)?
The number of molecules is approx. 12.10.e+23.
How many molecules of bromine are present in 120 grams of bromine gas?
To determine the number of molecules in 120 grams of bromine gas, you first need to calculate the moles of bromine using its molar mass (molar mass of Br2 = 159.808 g/mol). Then, use Avogadro's number (6.022 x 10^23) to find the number of molecules in that many moles of bromine gas.
How many grams in 4 moles of Na OH?
40*4=160g
How many atoms of bromine are in 2.6 moles of bromine?
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.
How many atoms of bromine will you multiply to get moles of bromine?
To convert atoms of bromine to moles of bromine, you would need to divide the number of atoms by Avogadro's number (6.022 x 10^23). So, to get moles of bromine, you would divide the number of atoms by Avogadro's number, not multiply.
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.
