We can find the volume of base needed by dividing moles of OH– required by the concentration of base used. Solve (a) (b) (c) Think about It. Because sulfuric acid has two H+ ions (it is a diprotic acid), we need twice as many moles of OH– to neutralize it compared to the same concentration of a monoprotic acid such as HNO3. 4.59.

Total mass of Zn = Total mass of penny - Total mass of Cu (7) Now, all of the zinc that is present in the penny is in the core. Since 99.2% of the total mass of the core is due to zinc, you can use your previously calculated value for the total mass of Zn and calculate the mass of the core: Total mass of Zn = 0.992 (Total mass of core) (8)
