QUESTION: Problem 97P
What mass % of ammonium sulfate, ammonium hydrogen phosphate, and potassium chloride would you use to prepare 10/10/10 plant fertilizer (see Problem 3.140)?
ANSWER:Solution 97P:
Here, we are going to determine the mass % of ammonium sulfate, ammonium hydrogen phosphate, and potassium chloride which has used to prepare 10/10/10 plant fertilizer .
Step 1:
Calculation of the moles of N, P and K from the 10/10/10 plant fertilizer.
Consider, the mass of the sample =100 g
Then 10:10:10 indicates, 10 g N, 10 g and 10 g
Therefore,
Moles of N =(10 g N) =0.713776 mol N
Moles of =(10 g
)
)
(
) =0.14090 mol P
Moles of =(10 g

(
)= 0.21231 mol K
