Get started for freeA student combines \(60.0 \mathrm{~mL}\) of \(0.250 \mathrm{M} \mathrm{NaOH}\) with \(60.0 \mathrm{~mL}\) of \(0.125 \mathrm{M} \mathrm{NaOH}\). What is the \(\mathrm{NaOH}\) molar concentration in the resulting solution?
What do we mean when we say that solute particles diffuse through a solution?
Give precise instructions to your laboratory assistant as to how to prepare \(1.00 \mathrm{~L}\) of a \(1.00 \mathrm{M}\) aqueous solution of sucrose, \(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}\). Remember that she will be measuring out the sucrose in grams. She has available a 1-L volumetric flask.
You have two solutions, one \(0.650 \mathrm{M}\) iron(III) nitrate and the other \(1.500 \mathrm{M}\) ammonium carbonate. (a) Write a net ionic equation for the precipitation reaction that occurs when these solutions are combined. (b) If you pour \(200.0 \mathrm{~mL}\) of each solution into the same flask, what is the theoretical yield of the precipitate in grams? (c) What is the molar concentration of the excess reactant ion?
A solution of a particular solid solute in water has a concentration of \(25.0\) mass \(\%\). (a) Given \(100.0 \mathrm{~g}\) of this solution, how many grams of solute do you have? (b) Given \(48.0 \mathrm{~g}\) of this solution, how many grams of solute do you have? (c) How many grams of this solution do you need to obtain \(56.5 \mathrm{~g}\) of solute?
