Question
Questions below:
If 26.98 g of Aluminum totally react with 106.37 g of chlorine gas, how many grams of Aluminum chloride are obtained? Antimony has 2 naturally occurring isotopes with abundances & masses in the table below. There are many Nitrogen Oxides. The first compound has 46.68% by mass nitrogen & 53.32% by mass oxygen & the second 30.45% by mass nitrogen & 69.55% by mass oxygen. The percentage ratio of 1.14g of oxygen per gram of nitrogen which are consistent with Dalton's Law of multiple proportions Oxygen has three stable isotopes with abundances & masses given in the table below
Explanation / Answer
2) for copper
63.5=(69.1*62.9+64.8*x)/100
=>x=30.92 % =3.092*10^1 %
