Help please with mixing 54 ml of nic into…..

Hi I am in need of assistance on how many drops of 54 ml nic do I drip into a 30 ml bottle of zero nic juice. I use 6 drops and I am trying to ween myself off so I can quit the nic altogether. I just dripped 3 normal drop sizes into my 30 ml bottle. How much nicotine is that in my 30ml bottle of full ejuice. ? 0.3 %??? I don't know. I am coughing way too much these days. Thanks
