When 85.0 mL of 0.250 M Ba(OH)2 solution is added to 85.00 mL of 0.250 M Al (NO3)3 solution, a white gelatinous precipitate of Al(OH)3; is formed. Assuming 100% yield, (a) what mass (in grams) of Al(OH)3 is formed? (b) what is the molarity of each of the ions Ba2+, OH-, Al3+, NO3- in the resulting solution?
A chemist dissolves a 1.497-g sample of a type of metal (an alloy of Sn, Pb, Sb, and Cu) in nitric acid, and metastannic acid, H2SnO3, is precipitated. She heats the precipitate to drive off the water, which leaves 0.4909 g of tin(IV) oxide. What was the percentage of [in in the original sample?
68. Aluminum ion may be precipitated from aqueous solution by addition of hydroxide ion, forming Al(OH)3. A large excess of hydroxide ion must not be added, however, because the precipitate of Al(OH)3 will redissolve as a soluble compound containing aluminum ions and hydroxide ions begins to form. How many grains of solid NaOH should be added to 10.0 mL of 0.250 M A1Cl3 to just precipitate all the aluminum?
can you help me please?

Industrially, vanadium metal, which is used in steel alloys, can be obtained by reacting vanadium(V) oside with calcium at high temperatures: SCa• V;0g- SCao+ 2V In one process, 1.540 x 10'gof V;O; reat with 2.090 x 1eg Ca. (a) Calculate the theoretical yield of V. (b) Calculate the percent yield if 805.0 g of V are obtained. Report your answers to the correct number of significant figures.
A 12.63 g sample of calcium ore was dissolved in HCl and gravimetrically analyzed, through the precipitation of calcium into CaC2O4 · H2O. The precipitate was filtered, washed, dried, and ignited at 500 oC until the weight was constant, giving a final mass of 2.35 grams pure CaCO3 (100.087 g/mol). Calculate the % Calcium (40.078 g/mol) in the sample.

A sample of processed meat scrap weighing 4.000 g is digested with concentrated H2SO4 and Hg(catalyst) until the N present has been converted to NH4HSO.. This is treated with excess NAOH , and the liberated NH3 is caught in a 100-ml of H2SO4 ( Iml = 0.01860 g Na,O). The excess acid requires 57.60 ml of NaOH ( Iml = 0.12660 g potassium acid phthalate, KHCaH.O4). Calculate the percentage protein in the meat scrap
