Im not sure if this is the correct place to post this so please move in necessary.

I am trying to make a 5000ppm N solution using urea(46-0-0), i would love for someone to proof my math here, I am getting a different value when using online calculators.

So here is my math, please correct me:

1gram urea into 1 liter of water will provide 460ppm(mg/l) N

5000ppm/460ppm= 10.87g Urea

So 10.87g urea into 1 liter will add 5000ppm Nitrogen.

Is this correct?

Looks OK to me.
