- Oct 22, 2017 · solution concentration? Answer First, we must convert the 200 mL to liters: Since 1000 mL = 1 L We can write that, 200 mL x 1L/1000 mL = .20 L Therefore, Molarity = mol/L = .3 mol glucose/.20L = 1.5 mol/L = 1.5 M glucose. Now, if we modify the above example by changing the moles of glucose to grams of glucose, we will get the following question:
- Sep 05, 2016 · Give the number of moles of electrons supplied by SO2 for reducing one mole of K2Cr2O7. 25 mL of a solution containing HCl was treated with excess of M/5 KIO3 and KI solution of unknown ...
The Solubility Product Expression. Silver chloride is so insoluble in water (.0.002 g/L) that a saturated solution contains only about 1.3 x 10-5 moles of AgCl per liter of water.
- Our online molarity calculator makes calculating molarity and normality for common acid and base stock solutions easy with most common values pre-populated.

May 25, 2013 · A 0.5 M MgCl₂, contains 0.5- moles in a Liter (1000-mL) of solution. 1 mole is 95.3g of MgCl₂. Since you didn't say what volume of the solution you want, we can't give you the exact procedure for its production. Generally though, Molarity = (mass of solute)/ (molar mass of solute x Volume of solution)
