翻译：如果原子量为27的铝（Al ）与原子量为16的氧（O）结合,形成复合氧化铝（Al2O3 ）,将需要多少氧气与铝52克完全反应?
4Al + 3O2¬ = 2Al2O3
4*27 3*2*16 2(27*2+16*3)
108 96 204
52g x
所以：108/52=96/x,得x=46.22g
所以需要的氧气质量为46.22克
擦~明明是道化学题好不好？不要欺负我不认识英文！
2AI+3O2=2AI2O3
AI物质的量=52/27 (mol)
所需 O2物质的量=(52/27)*(3/2)=26/9 (mol)
所需氧气的质量=26/9*32=92.444444444444444444444444克
问的是要多少氧气才能完全反应52g的铝，方程式：4Al+3O2=2Al2O3，需要氧气量=52*6*16/4*27=46.2g
