A 1 molar solution is a solution in which 1 mole of a compound is dissolved in a total volume of 1 litre. formula weight of glucose is 180.2 - measure 180.2 g of glucose into a graduated cylinder, then add water until the final volume is equal to 1 L If you dissolve 180.2g of glucose in a final volume of 1 litre, you have made a 1M glucose solution.
For example, a 0,2 M sodium chloride solution: - calculate the molar mass of NaCl from the atomic weights of the elements: 22,98976928 + 35,453 = 58,443 (rounded value for laboratory use) - 58,443/0,2 = 11,6886 g - weight 11,6886 g of NaCl (reagent quality) and dissolve in ca. 800 mL distilled (or deionized) water in a 1L volumetric flask. - put the volumetric flask in a thermostat - after reaching a temperature of 20 0C (or another temperature if it is marked on the flask) add distilled (or deionized) water to the mark - stir the content (with the flask cap, of course)
Take 68.6 gms ofsucorse, dissolve in some water , make into 1000 ml
this will be 0.2 mol/ litre solution
you have to insert nana habib soulution
100 mL of solution 1 M mixed with 900 mL distilled water
combine 100 mL 6 M HCl with 500 mL H2O
HCl has a molar mass of 36.461 grams per mole. This means that 72.922 grams of HCl are needed per liter of water to make a solution that has a concentration of 2M.
the PH will be the same
Let me translate the question: I think you are asking how to make a 0.1 molar solution of Na2S2O4. Molarity is moles of solute divided by liters of solution. To make this easy, let's assume you want to make one liter of the solution. That means you need to dissolve in 0.1 moles of Na2S2O4 into one liter of water to make a 0.1 molar solution. The formula weight of Na2S2O4 is 174.1 grams per mole so 0.1 moles of it is 17.41 grams. Therefore you would need to dissolve 17.41 grams of Na2S2O4 into one liter of water to make a 0.1 molar solution.
100 mL of solution 1 M mixed with 900 mL distilled water
The term molar it refers a form to know the concentration of a solution, and it is equivalent to a molar unit in a litre of solvent 1 Molar (1M) = 1 mole (molecular weight from the structure you are interested in) / 1000 mL or 1 L. Milimolar is the thousandth part from a solution 1M
The formula mass of KCl is 75.5 so when 94.375g of it are dissolved in i litre water the solution prepared is 1.25 molar
6.023 X 1023 particles make up a 1M solution.
combine 100 mL 6 M HCl with 500 mL H2O
Only a compound has a molar mass not a solution.
Ten milliliters is a hundredth of a liter. So in a two molar solution, you would have .02 moles in 10 ml.
HCl has a molar mass of 36.461 grams per mole. This means that 72.922 grams of HCl are needed per liter of water to make a solution that has a concentration of 2M.
I suppose that this solution doesn't exist.
the PH will be the same
What volume do you want to make. To make 1 liter, you take the 185 g (the molar mass) and dissolve in enough solvent to make the final volume 1 liter.
