Explanation:lol
<span>NPK ratio system is a conventional shorthand for the ratio of the nitrogen N), phosphorus (P) and potassium (K) in a fertilizer. It actually shows amount of P</span>₂O₅.
If we use 100 kg of P₂O₅:
m(P₂O₅) = 0,15 · 100 kg.
m(P₂O₅) = 15 kg.
m(P₂O₅) : M(P₂O₅) = m(P) : 2M(P).
15 kg : 142 = m(P) : 62.
m(P) = 6,55 kg.
ω(P) = 6,55 kg ÷ 100 kg · 100% = 6,55%.

<span>1.)Cathode 2.)Atom
For the first part, the cathode is the basically like the negative side or terminal. On batteries (cylindrical cells like the ones you get out of the store for your TV remotes or wireless computer mouse) usually have the cathode on the bottom.
The atom is known as the smallest physical form of any object (other than protons, neutrons, and electrons).</span>
