WebThe initial solution contained twice as much sulfuric acid as sodium hydroxide because two moles of sodium hydroxide react with one mole of sulfuric acid. n(H2SO4) = 0.009592 mol / 2 = 0.004796 mol; 70.00 mL, or 0.07000 L, of sulfuric acid solution was used in the titration. As a result, the original solution's molar concentration of sulfuric ... WebPercent concentration by mass is defined as the mass of solute divided by the total mass of the solution and multiplied by 100%. So, c% = msolute msolution ⋅ 100%, where msolution = msolvent + msolute There are two ways to change a solution's concentration by mass Adding more solute - making the solution more concentrated;

WebPROBLEM 6.1.5. Calculate the number of moles and the mass of the solute in each of the following solutions: (a) 2.00 L of 18.5 M H 2 SO 4, concentrated sulfuric acid. (b) 100.0 mL of 3.8 × 10 −5 M NaCN, the minimum lethal concentration of sodium cyanide in blood serum. (c) 5.50 L of 13.3 M H 2 CO, the formaldehyde used to “fix” tissue ... WebMar 14, 2016 · As the initial concentration of H 2 SO 4 increased from 0.5 to 2.5 mol/L, the residual H 2 SO 4 in the strip solution increased from 0.26 to 2.1 mol/L. Greater residual sulfuric acid in the strip solution means that more aqueous ammonia will be consumed during the subsequent vanadium precipitation process.
