Can someone help me with this chemistry question?
here is the question that i have been struggeling with
A sample of copper ore is obtained from a 5 gram sample of copper carbonate. the 5g is treated with 25ml of .25mol/L of H2SO4. this mixture is allowed to stand until the reaction is complete. all of the disolved CO2 is driven off by heat. the resultant solution is then titrated with 0.25mol/L solution of NaOH. 17.3ml of the NaOH is required to neutralize the remaining acid (from the copper and acid reaction). assuming that the copper carbonate is the only substance present in the reaction with the acid; calculate the percentage by mass of copper in the copper ore?
