Assuming that copper metal can be extracted from a given mass of any ore at the same cost, which of the two minerals could be mined profitably for copper? Malachite or chalcopyrite?

under suitable conditions, thiourea is oxidized to sulfate by bromate:
3CS(NH2)2 + 4BrO3- + 3H2O --- 3CO(NH2)2 + 3SO4 + 4Br- + 6H+
a 0.0 715g sample of material was found to consume 14.1mL of 0.00833 M KBrO3. What was the % purity of the thiourea sample?
P.S this is analytical chem..... Thanks for the answer in advance

Answer in units of m

When left over a flame a marshmallow is consumed in a combustion reaction. Assuming a marshmallow is made of entirely sucrose, C12H22O11, and after combustion no residual solid remained, the following chemical equation describes this reaction.

C12H22O11(s) + 12 O2(g) → 12 CO2(g) + 11 H2O(g)

Using the equation above, if the marshmallow contains 6.19 g of sucrose and is the limiting reactant, what is the theoretical of H2O?
