The molecular mass of ammonia is 17. a. How much is the GMM of ammoni

1.	The molecular mass of ammonia is 17. a. How much is the GMM of ammonia? b. Find out the number of moles of molecules present in 170g of ammonia. c. Calculate the number of ammonia molecules present in the above sample of ammonia?
Answer» a. GMM of ammonia (NH₃) = 14 + 3 × 1 = 17g = 1GMM b. Number of mole molecules = \(\frac{Mass}{GMM}\) = \(\frac{170}{17}\) = 10 c. Number Of molecules = Mole × 6.022 × 10²³ = 10 × 6.022 x 10²³

The molecular mass of ammonia is 17. a. How much is the GMM of ammonia? b. Find out the number of moles of molecules present in 170g of ammonia. c. Calculate the number of ammonia molecules present in the above sample of ammonia?

Answer»

a. GMM of ammonia (NH₃) = 14 + 3 × 1 = 17g = 1GMM

b. Number of mole molecules = \(\frac{Mass}{GMM}\) = \(\frac{170}{17}\) = 10

c. Number Of molecules = Mole × 6.022 × 10²³

= 10 × 6.022 x 10²³

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example.
