To what volume (in milliliters) should you dilute 100.0 mL of a
4.50 M solution of CaCl2 solution to obtain a 0.900
M solution of CaCl2?
Express the volume to three significant figures and include the
appropriate units.
To what volume should you dilute 133 mL of an 7.95 M CuCl2
solution so that 49.0 mL of the diluted solution contains 4.27 g
CuCl2? Express your answer in milliliters.
Please answer all three thank you!
Part A
To what volume should you dilute 155 mL of an 8.60 M CuCl2
solution so that 60.0 mL of the diluted solution contains 5.9 g
CuCl2? Answer in mL
Part B
What is the molarity of an aqueous solution that is 5.69 % NaCl
by mass? (Assume a density of 1.02 g/mL for the solution.)
Part C
Ocean water contains 3.5 % NaCl by mass. How much salt can be
obtained from...
A 5.00 mL volume of a 0.60 M solution of phosphoric acid,
H3PO4(aq), reacts with 45.00 mL of 0.25 M NaOH(aq) according to the
reaction below. The temperature of the solution rises from 26.0 °C
to 28.0 °C. Assume the volumes of the solutions are additive, the
density of the final solution is 1.10 g mL–1 , the heat capacity of
the solution is the same as water and the water produced by the
reaction does not affect the volume...
