Pls give me the answer and explain to me ....... Thank you!!!!! Question: Coppre have 2 isopos (63 Cu and 65 Cu)........... And the >>Reality mass<< is 63.15 then ?%--->63 Cu 更新: best in 中文回答....thx!!!!!!!!!
最佳解答:
let x be the % of 63 cu 63x + 65 ( 1-x) = 63.153 63x + 65 - 65x = 63.153 1.847 = 2x x = 0.9235 therefore, 63 cu = 92.34%
其他解答:
你可以設63 Cu既relative atomic mass係x 咁就會出左一條equation出泥: 63*x+65*(1-x)=63.15 咁因為設左63 Cu既mass係x啦咁所以65 Cu既mass就會係65*(1-x) 63x+65-65x=63.15 65-63.15=65x-63x 2x=1.85 x=0.925 咁所以63Cu 既relative atomic mass就會係92.5% 希望幫到你!!(;
