Is it normal to black out after 3 shots and a white claw?

I am 18 and drink about every weekend, usually 3 or so drinks/shots. This past weekend I was with friends and I had 3 shots of vodka over the course of an hour, as well as one white claw throughout that hour and then about two hours after I started drinking I blacked out for about 4 hours. I had eaten a lot that day also, so I wasn’t drinking on an empty stomach. I also did not smoke at all that night. This was my first time blacking out, and I have been drinking moderate amounts since I was 15. Is this normal?
