How do I delete chrome from apple MacBook Air

See the instructions in the Mac section of: https://support.google.com/chrome/answer/95319?co=GENIE.Platform%3DDesktop&hl=en

Drag it to the trash and empty.

Open Finder and select Apps on the left pane. Then scroll down till you get to the Chrome app. Drag it to the Garbage can and empty the can :)
