Question

calculate the no of sulphur molecular s(8) in 16g of solid sulphur atomic mass 324

Answer 1

Sulphur atomic mass given 32

=> Sulphur molar mass = 32 g

=> Sulphur molecule molar mass = 8 × 32

= 256

Given mass = 16 g

Mole = given mass (g)/molar mass

=> Mole = 16/256

=> Mole = 0.0625

Number of molecules = mol × Avogadro number

Avogadro number = 6.022 × 10²³

=> Number of molecules = 0.0625 × 10²³

=> Number of molecules = 0.376375 × 10²³

= 3.76375 × 10²²

Hope it helps dear friend ☺️✌️
