Answer:
nitric acid will be if you get you will pixel purpose
Answer: (The composition of a bituminous coal by percentage is roughly: carbon [C], 75–90; hydrogen [H], 4.5–5.5; nitrogen [N], 1–1.5; sulfur [S], 1–2; oxygen[O], 5–20; ash, 2–10; and moisture, 1–10.)
15 - 30 - 15 indicates the percentages of Nitrogen - Phosphorus - Potassium respectively. Thus, the fertilizer has 30% Phosphorus (by mass)
Mass of phosphorous = 5 * 0.3
= 1.5 grams
Atomic mass of Phosphorous:
31
moles = mass / Ar
moles = 1.5 / 31
moles = 0.048 mol
