What is the molecular formula of Calcium sulphate, Sodium nitrate, Magnesium oxide, Potassium carbonate, Ammonium sulphide, Hydrogen sulphate, magnesium nitrate and Silicon oxide ? Guys please help me
Once who help me I will mark as a briently.

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.
