If carbon (C,with an atomic weight of 12,combines with oxygen (O),with an atomic weight of 16,to form carbon dioxide (CO2),how many grams of carbon would react with 288g of oxygen?
原题翻译:如果碳(原子质量为12)与氧(原子质量为16)反应生成二氧化碳,多少克碳与288克氧气恰好完全反应?
化学反应方程式为:
C + O2 == CO2
12 32
x 288
12/32=x/288
x=108
答需要108克碳与288可氧气恰好完全反应.
需要108g的炭,288g的o对应9mol二氧化碳,需要炭12*9=108g
(288/(16*2))*12=108 gram
