How do you prepare 0.1n hypona2s2o4?
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.
How would a solution that is labeled 5.0 m would be read as?
5.0 molar
What is the molarity when water is added to 2 moles of sodium chloride to make 0.5 liter of solution?
Molarity is calculated as moles of solute divided by volume of solution in liters. In this case, you have 2 moles of sodium chloride in a 0.5 liter solution. So the molarity would be 2 moles / 0.5 L = 4 M.
The pH of a 0.1 molar aqueous solution of HCl would equal -?
1
How do you prepare 0.5M ammonium molybdate?
Ammonium molybdate is (NH4)2MoO4. Its molar mass is 148g/mol. A 0.5M solution will have half a mole per liter of water. Half a mole of ammonium molybdate is 74g, so you would measure out 74g of it, and dissolve it in a liter of water.
Why would you expect a 1.5 m CaCl2 solution to have a lower freezing point than a 1.5 m NaCl solution?
CaCl2 has more particles when dissolved
How many moles of potassium carbonate are in 10.0mL of a 2.0 M solution?
Ten milliliters is a hundredth of a liter. So in a two molar solution, you would have .02 moles in 10 ml.

How would you create a 10 molar solution to total 100 ml for compound whose molecular weight is 10 grams?
By definition, a 10 molar solution contains 10 moles of the solute per liter of solution. Therefore, since 100 ml is 1/10 of a liter, 100 ml of such a solution would contain one mole of the solute. Physically, this would normally be accomplished by adding 10 grams, stated to be one mole of the solute, to a 100 ml volumetric flask, then adding pure water until the mark on the neck of the flask is reached.
How you would make a 0.5 molar solution of urea with a final solution volume of 0.5 liter.?
Dissolve 15,015 g urea in 0,5 L demineralzed water; work with a thermostat at 20 oC and a volumetric flak.
How many molecules of glucose would be in 1 liter of the 1 m?
if you mean a 1 litre, 1 molar solution, then you have 1 mole. you just need to multiply by avagadro's number
Potassium fluoride (KF a salt has a molecular weight of 58.10 grams. How many grams would be needed to make 1.0 liter of 5.0 molar salt solution?
290 grams
How would a solution that is labeled 5.0 m would be read as?
5.0 molar
How would a solution that is labeled 5.0m would be read as?
5.o molar
How would a solution that is labeled 5.0 M be read as?
5.0 molar
How do you express concentrations of solutions?
A solution concentration maybe expressed as g/liter but it is much more common and scientifically desired to express the concentration as a molarity or normality. So 36.5 g per liter of HCl would be 1 molar or 1 normal.
How would you make a 1.25 molar solution of potassium hydroxide?
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
