含N,P等元素的废水排入水体,能引发蓝藻疯狂生长,实验分析得出蓝藻的组成为:C-35.80%,O-49.50%,P-0.87%,N-6.31%,该蓝藻的实验式为______(要过程)谢谢

问题描述:

含N,P等元素的废水排入水体,能引发蓝藻疯狂生长,实验分析得出蓝藻的组成为:C-35.80%,O-49.50%,P-0.87%,N-6.31%,该蓝藻的实验式为______(要过程)谢谢

COPN的原子数比为
C:O:P:N = (35.80%/12) :(49.50%/16) :(0.87%/31):(6.31%/14)
= 3:3:0.02:0.45
= 300:300:2:45
该蓝藻的实验式为
C300 O300 P2 N45
