What is the concentration of lithium ions in 0.415 M Li₂HPO₄?

What volume (mL) of 0.70 M Sodium hydroxide (NaOH) is needed to neutralize 270 mL of 0.40 M Sulfuricacid (H2SO4)?2 NaOH + H2SO4 Na2SO4 + 2 H2O

What are the individual ion concentrations and the total ion concentration in 0.66 M Mg(NO3)2?

One of the main acidic components of acid rain is sulfuric acid, H₂SO4. Assuming sulfuric acid is the only acid in the acid rain, what volume (in mL) of 0.000915 M KOH would be required to titrate a 45.00 mL sample of acid rain with an H₂SO4 concentration of 1.230 × 10-4 M? Volume mL

If you require 30.51 mL of .1090 M NaOH solution to titrate 10.0 mL of HC2H3O2 solution, what is the molar concentration of acetic acid in the vinegar?

What volume (in L) of 1.6 M Na₃PO₄ would be required to obtain 0.56 moles of Na⁺ ions?

If the molarity of MgCl2 is 1.5 M, what is the concentration of chloride ions?

Concentration is measured by molarity (M), or moles per liter. Brackets are also used to symbolize molarity. For example, if 0.6 moles of HNO3 are dissolved in a liter of water, you would say [HNO3] = 0.6 M.   Because HNO3 is a strong acid, it dissociates almost completely in water. That means the concentration of H+ is very nearly equal to that of HNO3. What is [H+] if [HNO3] is 0.01 M?      The pH of a solution is equal to the negative log of H+ concentration: pH = –log[H+]  What is the pH of this solution?      What is the pH of a 0.6 M HNO3 solution?
