Question

calculate the number of molecules of sulphur S8 present in 16 gram of solid Sulphur​

Answer 1

Answer:

Calculate the number of molecules of sulphur (S8) present in 16 g of solid sulphur. ∴ 16 g of sulphur = 16 256 1 16 = moles = 0.125 moles 1 mole of S8 molecules = 6.023 × 1023 number of molecules ∴ 1 16 mole of S8 = 6.023 × 1023 number of molecules × 1 16 .

in french - Calculez le nombre de molécules de soufre (S8) présentes dans 16 g de soufre solide. ∴ 16 g de soufre = 16 256 1 16 = moles = 0,125 mole 1 mole de molécules S8 = 6,023 × 1023 nombre de molécules ∴ 1 16 mole de S8 = 6,023 × 1023 nombre de molécules × 1 16.

Answer 2

$\huge\mathfrak\green{answer!}$

To calculate molecular mass of sulphur:

Molecular mass of Sulphur (S8) = 8xMass of Sulphur = 8×32 = 256g

Mass given = 16g

Number of moles = mass given/ molar mass of sulphur

= 16/256 = 0.0625 moles

To calculate the number of molecules of sulphur in 16g of solid sulphur:

Number of molecules = Number of moles X Avogadro number

= 0.0625 x 6.022 x 10²³ molecules

= 3.763 x 10²² molecules
