Dilution Factor Chemistry Tutorial AUS-e-TUTE
2018-4-7 roughly calculate concentration of Fe 2+ in stock solution using the mass of iron we calculated: c = n ÷ V = (m/M) ÷ V ≈ (1/50) ÷ 5 = 0.004 mol L -1 dilution factor was 1 :250, so concentration of dilute solution = concentration of stock solution ÷ 250 = 0.004 ÷ 250 = 1.6 × 10 -5 mol L -1 which is approximately the same as that given in the question so our solution looks good.

Preparation of FeSO4 solution
To prepare 1000 mL of a 0.1 mol/L solution of Iron (II) sulfate we have to dissolve 27.8015 g of FeSO4×7H2O (100 % purity) in deionized or distilled water. After the solid is completely dissolved, dilute the solution to a final volume with deionized (distilled) water. Transfer the prepared solution to a clean, dry storage bottle and label it.

Molarity Calculator [with Molar Formula]
2021-2-10 Molar mass is the mass of 1 mole of the solute. It is expressed in grams per mole. It is a constant property of each substance for example, the molar mass of water is approximately equal to 18 g/mol. Our calculator can also find the mass of substance you need to add to your solution to obtain a desired molar concentration, according to the formula

ChemTeam: Molarity Problems #11 25
2015-1-14 Problem #21: Commercial bleach solution contains 5.25% (by mass) of NaClO in water. It has a density of 1.08 g/mL. Caculate the molarity of this solution. (Hints: assume you have 1.00 L of solution; molar mass of NaClO 74.4 g/mol) Solution: 1) Determine mass of 1.00 L of solution: (1.08 g/mL) (1000 mL) = 1080 g

How to prepare a solution from stock solution
2019-2-10 A stock or standard solution is a solution in which you accurately know its concentration. You can make stock solutions in the chemistry laboratory or buy from chemical manufacturers. Once you have a stock solution, you can prepare solutions of lower concentration by diluting the concentrated stock solution.

It's hard not to experience iron and aluminum in our everyday lives. Iron ores are usually compounds of iron and oxygen, otherwise known as rust. Much of these ores were formed when the earliest photosynthesizing microbes began to pump oxygen into the earth's oceans. In a way, iron ores are fossils, so all iron and steel we use are made from fossils.
