#70. What mass of precipitate (in g) is formed when 20.5 mL of 0.500 M Cu(NO₃)₂ reacts with 40.0 mL of 0.500 M NaOH in the following chemical reaction? Cu(NO₃)₂(aq) + 2 NaOH(aq) → Cu(OH)₂(s) + 2 NaNO₃(aq) #84. What volume (in mL) of 0.2800 M HBr is required to neutralize 60.00 mL of 0.6000 M LiOH?

How many milliliters of 12.0 M HCl(aq) are needed to prepare 220.0 mL of 1.00 M HCl(aq)?

In the experiment, a student is given 2.94 g of a mixture containing anhydrous MgCl2 and KNO3. To determine the percentage by mass of MgCl2 in the mixture, the student uses excess AgNO3(aq) to precipitate the chloride ion as AgCl(s).    Starting with the 2.94 g sample of the mixture dissolved in water, briefly describe the steps necessary to quantitatively determine the mass of the AgCl precipitate.  The student determines the mass of the AgCl precipitate to be 5.48 g. On the basis of this information, calculate each of the following.(i) The number of moles of MgCl2 in the original mixture  (ii) The percent by mass of MgCl2 in the original mixture

If 20.6 grams of an aqueous solution of magnesium nitrate, Mg(NO3)2, contains 2.91 grams of magnesium nitrate, what is the percentage by mass of magnesium nitrate in the solution? % Mg(NO3)2

What is the molarity of a solution that contains 2.30 g of H2C2O4⋅2H2O in 200. mL of solution?
