What is the molarity of a solution that contains 3.25 moles of nano3 in 250. ml of solution_

Often, concentration of solution is described qualitatively, through the use of such words as dilute and On the other hand, a solution can be concentrated by adding solute or removing solvent. Quantitative Description. Molarity is defined as the number of moles of solute per litre of solution3. Electrical conductivity of solutions, their osmotic pressure, boiling and melting points depend not only upon their concentration but also upon their ionization percent n In solutions of weak electrolytes equilibrium is maintained between ions and molecules of a substance. 18g / mole.Sep 23, 2008 · Remember concentration = moles divided by volume in litres. So in a 250 ml 3M solution you will have 3*.25 = .75 moles H2SO4. So the mass of H2SO4 = moles * MW = 98 * 0.75 = 73.5g. Now a 50% solution (I assume by weight) will contain half H2O and half H2SO4. So the number of grams of 50% solution that will give you 73.5g H2SO4 = 147g. Find solutions for your homework or get textbooks.
