Question

calculate number of atoms is each of the following . average atomic mass:N=14, S=32
a. 0.4 mole of nitrogen
b. 1.6 g of sulfur​

Answer 1

Explanation:

Given : Molar Mass of N = 14, S =32

To find, : Number of atoms

Sol : Ans.1) Number of molecules = No. of moles x Av

Number of molecule = 0.4 x 6.023 x 10²³

Number of molecule = 2.4092 x 10²³m

Number of atom = Number of molecule x Atomicity

Number of atom = 2.4092 x 10²³ x 1

Number of Atom = 2.4092 x 10²³

Ans.2) Number of molecule = No.of moles x Av

Number of molecule = 1.6 x 6.023 x 10²³

Number of molecule = 9.6368 x 10²³

Number of Atom = Number of molecule x Atomicity

Number of atom = 9.6368 x 10²³ x 1

Number of Atom = 9.6368 x 10²³.
