誰會解這題~~~從混合物中算出CuO跟Cu2O的克數

[應化系 10]

A certain mixture of CuO and Cu2O weights 10.50 g total. Complete reduction of this mixture produces 8.66 g of pure metallic Cu. Determine the amounts of CuO and Cu2O in the original mixture.

[Morris 10]

這應該是 general chemistry 第一章或第二章化學計量的題目吧

令CuO=X，Cu2O=(10.5-X)

則由題意得 64X／(64+32) + 128(10.5-X)／(128+32) = 8.86

剩下應該就自己可以解了

大家看看吧!!答案在這!!我解出來了!!!大家也算看看ㄅ

(Hint: Set g of CuO equal to x and g of Cu2O equal to y. Then find the moles of Cu from each.) Ans: 3.05 g Cu2O; 7.45 g CuO

這題就是高二上的化學基本題啊
