Explanation:
okay these are simple stoich
1. 564 g Cu 1 M Cu
---------------- x. -------------- = 19.45 M Cu
1 29 g Cu
2. 12.3 g CO2 1 M CO2
----------------- x ------------------ = .28 M CO2
1 44.01 g CO2
3. 89 g Pb(CH2COO)4 1 M
------------------------------ x --------------------- = .2 M Pb(CH2COO)4
1 439.34 g
4. 6.6 M ZnO 81.4
----------------- x ---------------- = 537.24 g ZnO
1 1 M
5. 5.4 M k2SO4. 174.3 g
------------------- x ------------------= 941. 22 G k2SO4
1 1 M
