There are mol of bromide ions in 1.00 l of a 0.300 m solution of albr3.

The equation for molarity of a solution is molarity equals moles divided by liters. Knowing that the solution is .300 M, and there is only one liter, you can use simple algebra to find that there is .3 mols of AlBr3 in the solution. Since moles can be simplified in a chemical equation to a whole number ratio, in this case it would be one mole of Al to three moles of Br. since there are three moles of Br in the compound, all you have to do is multiply the mols of AlBr3 by 3-- equaling to .900 mols of bromide ions.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
