Problem- Determine the molarity of a solution containing 4 moles of Li2SO4 in 2L solution, 2.4 moles of CuSO4 in 1.5L solution, and 3.7 moles of NaOh in 4.2L solution.
Determine the volume of the following solutions: 0.250M solution of CuSO4 containing 5 moles of solute, 2.0M solution of CaCL2 containing 3.2 moles of solute, and 1.5M solution of Na2O containing 0.25 moles of solute.
How many moles of solute are present in each of the following solutions: 3.0L of 2.4M Ca(OH)2, 500 mL of 6.0M H3PO4, and 4.0L of 0.750M KCL. Please show the following steps with their individual solutions, Thank you for this consideration.

Using the tools you have at hand (a melting point apparatus and TLC setup), what other data could you collect to test your hypothesis from part a? Give two possibilities.
Why don't we observe the deBroglie wavelength of everyday macroscopic objects (such as a moving car or a thrown baseball)? The wavelength is too small relative to the size of macroscopic objects to be observed.
A. Write a net ionic equation . B- for the reaction in part a, write the equilibrium constant from a consideration of Kb and Kw. C- calculate the h3o^+ for a 0.45 M nh4cl solution . D- calculate the percent of hydrolysis of 0.45 M NH4Cl.
Two of the Group 12 elements exhibit very similar chemistries to one another, while the chemistry of the third is somewhat different. Identify the Group 12 element whose chemistry is different from the other two Group 12 elements.
The models you have just studied represent achiral molecules. Their mirror images are identical. They are optically inactive. Any molecule that has a plane of symmetry is achiral.
