6%. Find the mass of nitrogen supplied to soil by 5 kg of urea, CO(NH2)25. Find the mass of nitrogen supplied to soil by 5 kg of urea, CONHan(O16, N-14, C12, H-1)

Answer»

molar mass of urea = 16+12+16+16 = 60

% of nitrogen by mass in 1 mole of Urea = 28/60 = 46.66%

now mass of N in 5g urea = 5*(46.66/100) = 2.33g
