Q1) Determine the molarity (molar concentration) of a solution that contains 52.63g of SrCl2 dissolved in 500.0mL. Show your process, with units and significant digits.
Q2) In a titration experiment, a HCl solution was prepared by adding 125.0 mL of a 10.00 mol/L stock solution to enough distilled water to make a final 500.0 mL of a diluted solution. What is the concentration of this diluted HCl solution? Show your process, with units and significant digits.
Q3) In a titration experiment, 16.74 mL of a 2.500mol/L solution was needed to neutralize 30.00 mL of a NaOH solution with unknown concentration. Determine the concentration of the NaOH solution. Show your process, with units and significant digits. HCl(aq) + NaOH(aq) --> NaCl(aq) + H2O(l)
Q4) A solution was prepared with 65.00mL of distilled water and 2.93g of copper (II) nitrate. This aqueous solution was mixed with 45.00mL solution of 0.587mol/L sodium sulfide. What mass of precipitate will be produced?
