The combination reaction of sodium metal and chlorine had to form sodium chloride is represented by this equation:
2Na+Cl2--> 2NaCl
If 5 g of sodium metal reacts completely with excess chlorine gas, an 11.5 g of Nacl is actually obtained what is the precent yield. I know that the actual yield. How do i find the theoretical yield so I can put it in the percent yield equation.
