How to Calculate Potassium Mass in a Bag of N-P-K Fertilizer

What is the ratio of Potassium per 100 g of N-P-K fertilizer with an analysis of 3.1.3 (42)?

Ratio of Potassium per 100 g of fertilizer

The ratio of potassium per 100 g of fertilizer is 3%. The analysis of the fertilizer, given as 3.1.3 (42), represents the percentage of nitrogen (N), phosphorus (P), and potassium (K) present in the fertilizer. In this case, the ratio of potassium is 3. This means that for every 100 g of fertilizer, there are 3 g of potassium.

What is the total Potassium mass in the 25 kg bag of N-P-K fertilizer?

Total Potassium mass in the bag

The total mass of potassium in the 25 kg bag of fertilizer is 0.75 kg (or 750 g). To calculate the total mass of potassium in the 25 kg bag, we need to determine the proportion of potassium in the bag.

First, let's convert the ratio of potassium to a percentage. Since 1 g is equivalent to 1%, we can say that 3 g is 3% of the 100 g of fertilizer. Therefore, the bag of fertilizer contains 3% potassium.

To calculate the total mass of potassium in the bag, we multiply the mass of the bag (25 kg) by the percentage of potassium. 25 kg * (3/100) = 0.75 kg

Therefore, the total mass of potassium in the 25 kg bag of fertilizer is 0.75 kg (or 750 g).
