Meadow, with an area of 1,500 square meters, was fertilized with 12 kg of urea. Urea contains 45% nitrogen. How much nitrogen accounted for per 1 m2?

Correct answer:

x =  3.6 g

Step-by-step explanation:

m=12 kg g=12 1000  g=12000 g  S=1500 m2 a=m/S=12000/1500=8 g/m2  p=45%=45100=0.45  x=p a=0.45 8=3.6 g
