Indicate the concentration of each of ion present in the solution formed by mixing
(a) 42.0 mL of 0.170 M NaOH and 37.6 mL of 0.400 M NaOH
(b) 44.0 mL of 0.100 M and Na2SO4 and 25.0 mL of 0.150 M KCL
(c) 3.60 g KCl in 75.0 mL of 0.250 M CaCL2 solution.
Assume that the volumes are addictive.
a soulution is prepared by mixing 25.0ml of .100M HCL and 2.00mL of .200M NaCl. what is the molarity of the chloride ion solution
When the liberated hydrogen gas is collected over water at 29 degrees celsius and 752 torr, the volume is found to be 343 mL. The vapor pressure of water at 29 degrees celsius is 30.0 torr. What is the mass percentage of aluminum in this alloy?
A solution is prepared by mixing 0.3355 mol of NaNO3 (84.995 g mol-1) with 235.0 g of water (18.015 g mol-1). Its density is 1.0733 g mL-1. What is the molality of the solution?
Can an ether molecule be made out of a methanol or ethanol molecule? Why or why not? What is the structure for 1-Octanol & Propane-1,2,3-triol?
A 270- flask contains pure helium at a pressure of 755 . A second flask with a volume of 485 contains pure argon at a pressure of 727 torr.
Assume your solution contains lead and iron but not silver or nickel. Explain how will you know that: - Either silver or lead is present ( that is, describe what you will see that will tell you at least one of these is there)
what is the minimun number of coulombs required to produce 1.06 mol of gold?
calculate the density and # of moles of a 10% Bromine Solution used in an experiment. Does the 10% refer to v/v or g/v in solution? I used 350 ul of the Bromine Solution
