An economical substitute for vitreous silica is a high-silica glass made by leaching the B2O3-rich phase from a two-phase borosilicate glass. (The resulting porous microstructure is densified by heating.) A typical starting composition is 81 wt % SiO2, 4 wt % Na2O, 2 wt % Al2O3, and 13 wt % B2O3. A typical final composition is 96 wt % SiO2, 1 wt % Al2O3, and 3 wt % B2O3. How much product (in kilograms) would be produced from 50 kg of starting material, assuming no SiO2 is lost by leaching

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
