我能看出你是想用宾语从句来完成这个句子：
你可以这样说：I can't make it clear whether we can make it.
这个句子中第一个 it 是形式宾语 真正的宾语是whether 引导的宾语从句.
意思是：“我们是不是能做,我现在还说不清楚!”

一句最好不要用2个CAN和2个MAKE吧，别扭。THAT 和OF去掉，你造的句？问题比较大。

Of去掉就OK了

I don't know whether we can make it.
I'm not sure whether we can make it.
应该就是要表达“我不是很清楚我们是不是能做到”的意思吧
