What is the molarity of a 16.8 percent by mass aqueous solution of KI with a density of 1.15 g/mL?Molarity:Solutions possess variable amounts of solutes and solvents. The amount of solute is always less than the amount of solvent. We can express the amount of ...
The given cesium chloride (CsCl) solution is expressed in molarity (0.711 M). The molarity of the solution can be interpreted as 0.711 moles of CsCl present in one liter of the solution. The problem wants to further express this concentration in terms of percent by...

You can also use it as a percent weight calculator and a percent volume calculator to determine the mass percentage and the volume percentage, respectively. Read on if you want to discover: What is mass by volume percent? How do I find the concentration of a solution? How to determine ...
What is the molarity of a solution made by dissolving 36.29 g of glucose in 1.50 L of solution? If you need to make 800 g of a 12.0% by mass glucose solution, what mass of glucose needs to dissolved into what mass of water? a. 109 g of...
% Change in Momentum [b]1. I do not understand how to do this question as part of my revision. can anyone help? ''Calculate the % change in the momentum of the lorry from loaded to unloaded whilst traveling at a constant velocity of 13.41m/s'' [b]2. Momentum = mass x velocity?
There are two numericals, 1. Density of Methanol is 0.793 kg/l. Find molarity. ANSWER is : Desity/ Molar mass = Molarity (UNDERSTANDABLE) In other numerical 2. Concentration of H2SO4 is 98% by mass having density of 1.84gm/ml. Calculate Molarity. here they used another formula. now my...
