Answer compare 1 mole of h2, 1 mole of o2, and 1 mole of f2. (a) which has the largest number of molecules? explain why. (b) which has the greatest mass? explain why.

Given-

one mole of , one mole of and one mole of .

a)  As each mole consists of same number of atoms or molecules i.e.

(6.022 ×)  , therefore one mole of , one mole of and one mole of have same number of molecules.

b) Mass of 1 mole of substance is known as its molar mass.

Thus , mass of 1 mole of = 2× (1.0 g/mol) = 2.0 g/mol

Mass of 1 mole of = 2× (16.0 g/mol) = 32.0 g/mol

Mass of 1 mole of = 2× (19.0 g/mol) = 38.0 g/mol

Therefore, 1 mole of ha sthe highest mass among the given options.
