How many moles are equivalent to 3.6x1024 formula units of MgBr2?
The answer is 5,978 moles.
Formula for magnesium bromide?
The chemical formula of magnesium dibromide is MgBr2.
What is the Molarity of a substance that contains 4.13 grams of magnesium bromide in 845 liters of a solution?
To find the molarity of the substance, divide the moles of the substance by the volume of the solution in liters. First, calculate the moles of magnesium bromide: Convert grams to moles by dividing the given mass by the molar mass of magnesium bromide (184.1 g/mol). Moles of magnesium bromide = 4.13 g / 184.1 g/mol = 0.0224 mol. Next, divide the moles by the volume of the solution in liters: Molarity = 0.0224 mol / 845 L ≈ 0.00003 M (rounded to 3 significant figures).
