To determine the purity of the seed, two samples of 50 g were taken in the first, there were 0.8 g of weeds and 0.3 g of damaged seeds, and in the second, 1.1 g of weeds and 0.4 g of damaged seeds. Determination of seed purity with an accuracy of 0.1% NOTE. Calculate the percentage of undamaged seeds in each sample and the arithmetic mean of the numbers found

Let us determine the weight of conditioned seeds in the first sample of seed:

50 – 0.8 – 0.3 = 48.9.

Let’s determine the percentage of conditioned seeds in the first sample:

48.9 / 50 * 100 = 97.8.

Let us determine the weight of the conditioned seeds in the second sample of the seed:

50 – 1.1 – 0.4 = 48.5.

Let us determine the percentage of conditioned seeds in the second sample:

48.5 / 50 * 100 = 97.

Determine the degree of purity of the seed:

(97.8 + 97) / 2 = 97.4.

Answer: The purity of this seed is 97.4%.
