Nitrogen molecules in 1.4 moles of n2

molecules

Explanation:

As per Avogadro's constant for atoms, one mole of an element/compound consists of atoms/molecules.

Thus, the number of molecules in “n” moles of an element and compound  is equal to the product of number of moles of the element and compound and  Avogadro's constant.

Thus, 1.4 moles of will have

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
