A fertilizer is advertised as containing 14.0% nitrogen (by mass). How much nitrogen is there in 4.15 kg of fertilizer?

I have tried this in many different way and I never get the right answer. How do I solve it this way? I can solve it to find the percent but not with the percent first.

What is 14 percent of 4.15 kg?
