How many mg of nicotine are in this vape juice?

I just got Mr. Salt-E vape juice, and I’m trying to figure out what the nicotine percent is and how many mg of nicotine are in a ml. The bottle says 45 mg/30 ml. Thanks!
Update: EDIT: I have the Suorin Air (I love it!) Also, I asked this question specifically because I know from vaping other peoples that this one isn't extremely high.

I know for a fact that this isn't insanely strong.

And I am trying to get off cigs, but I had only been smoking like one a day
