Mol = mass/Ar (relative Atomic Mass)
For Bromine Ar is 79.9 g/mol.
Mol= 0.476/79.9 = 5.96x10-3
.0326 moles
.467 mol of Bromine gas
Bromine exists as a diatomic gas. Thus, there are two moles of bromine atoms in 1 mole of bromine gas.
.75 moles times 64 grams/mols = 48 grams
One mole of Br2 has 6.023 x 1023 bromine molecules or 2 x 6.023 x 1023 bromine atoms.
.0326 moles
2,60x102 grams of bromine (Br) is equal to 1,627 moles Br2.
.467 mol of Bromine gas
2,9 moles of bromine is equivalent to 463,4432 g.
10,0 moles of bromine atoms contain 60,22140857.1023 atoms.Attention: valid for bromine atoms !.
24.5 mL of a solution 1.0 M bromine contain 0,0245 moles.
Since you are using 0.28 moles of AlCl3, you need 0.84 moles of Br, which is 67.24 grams.
Bromine exists as a diatomic gas. Thus, there are two moles of bromine atoms in 1 mole of bromine gas.
This is equivalent to 0,36 moles.
16 grams of oxygen how many moles is 0,5 moles.
The atoms in the reacts are always present in the products. There is one mole of bromine per molecule and .196 moles of the molecule. Thus, there will be .196 mols of bromine present after the reaction.
9 moles of bromine contain 54,2.10e23 molecules.
