Understanding the Fertilizer Label These three numbers represent the primary nutrients (nitrogen(N) - phosphorus(P) - potassium(K)). This label, known as the fertilizer grade, is a national standard. A bag of 10-10-10 fertilizer contains 10 percent nitrogen, 10 percent phosphate and 10 percent potash.

The percent composition is the percent by mass of each element in a compound. One mole of ammonia (NH3) contains one mole of nitrogen (N) atom and 3 moles of hydrogen (H) atoms. ... Thus, the molar mass of NH3 is the sum of the atomic masses of N and 3 times the molar mass of H.

About 78% of the atmosphere is Nitrogen. Nitrogen is element 7 on the Periodic Table and has an atomic mass of 14.01 g/mol. Nitrogen in the natural state exists as N2 molecules. This gives diatomic Nitrogen an atomic mass of around 28 g/mol.

The most useful quantity for counting particles is the mole. So if each coefficient is multiplied by a mole, the balanced chemical equation tells us that 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia. This is the conventional way to interpret any balanced chemical equation.

Explanation: In an ammonium ion (NH+4) ion, there is one nitrogen atom and four hydrogen atoms. Nitrogen has an atomic number of 7 , and hydrogen has an atomic number of 1 , and so the total atomic number of the hydrogens will be 1⋅4=4 . So, there will be a total of 7+4=11 protons.

Explanation of Solution The percent composition of nitrogen is 46.7%. The percent composition of compound is 100%. So, the percent composition of oxygen is (100−46.7)%=53.3%.
