Molarity (M) represents the moles of a solute per liter of a solvent. In this case, sucrose is the solute and water is the solvent. First, convert your 125g of sucrose to moles...molar mass of sucrose = 342.34 soo you have .365 moles of sucrose. Since you have exactly one L of solution, the molarity of the solution is .365 M Molarity (M) represents the moles of a solute per liter of a solvent. In this case, sucrose is the solute and water is the solvent. First, convert your 125g of sucrose to moles...molar mass of sucrose = 342.34 soo you have .365 moles of sucrose.

## Related Questions You prepare a solution by dissolving a known mass of solute (often a solid) into a specific amount of a solvent. One of the most common ways to express the concentration of the solution is M or molarity, which is moles of solute per liter of solution. 1 % DCPIP solution can be prepared by dissolving 1g of the dye in 100cm3 of water  See the two Related Questions to the left for the answer.The first is how to prepare a solution starting with a solid substance (and dissolving it). The second question is how to prepare a solution by diluting another solution. You prepare a solution by dissolving a known mass of solute into a specific amount of solvent. In solutions, M is the molarity, or moles of solute per liter of solution. For 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water you need water and sodium chloride. The purpose is to prepare a sample solution for analysis. It depends on how much you are trying to make and what you are diluting it from, but the formula for figuring it out is Molarity of starting solution times X (in which X is how much you will be adding) equals Molarity of the solution you are producing times its volume molisch reagent is prepared by dissolving 5g of alpha napthol in 100 ml alcohol Look at the bottle of HCl. It gives a molarity. then dilute to 0.25 M. Molarity = moles of solute/liters of solution or, for our purposes moles of solute = liters of solution * Molarity moles of AgNO3 = 0,50 liters * 4.0 M = 2.0 moles of AgNO3 needed -------------------------------------- You prepare 0.05mM from NaHC03 by first dissolving it. As you dissolve it in water, monitor the pH of the solution. The Internet does not list anything with the formula ZnSO4.7H20. it has to be prepared using methanol or ethanol at the concentration we required. moles of KCl=molarity of KCl solution * volume of KCl solution=4.0*1.00=4.0 moles  Your question does not make sense, an almost infinite amount of solution could be prepared if desired The molarity is figured out by the number of moles of NaOH over the number of liters of water. so if the molarity is 0.5M and there is 1.0L of water then there has to be 0.5 moles of NaOH in the solution.  Use the formula: MaVa = MbVb where a is the original and b is what you are making. (M = molarity and V = volume) Hydrochloric acid is prepared by dissolving hydrogen chloride gas in water. Hydrogen chloride is a covalent compound, but when dissolved in water it ionizes to form hydrogen ions and chloride ions as follows: By Kuldeep K. bansal INDIA See Related Questions to the left "How do you prepare a solution of a specific concentration?" Diluted Ammonia solution can be prepared by diluted strong ammonia solution with the appropriate quantity of purified water. to prepare 1N we have to dilute 40gms of NaOH in 1 litre of water as for NaOH normality =molarity so to prepare 0.1N NaOH we have to dilute 4gms of NaOH in 1 litre of water.. Is that 50 millimolarity? Thin that would be 0.05 Molarity Molarity = moles of solute/Liters of solution so, one needs to know how much volume or how much mass to help you. Iodine monochloride is soluble in alcohol, ether, acetic acid. ICl is prepared from iodine and chlorine. The past participle of prepare is (have or has) prepared. For example, "I have already prepared tonight's supper."
