Question

claculate the flolowing in o.25 mole of s8 no. of s8 mole no. of sulphur atoms no. ofbmoles of sulpher atom

Answer 1

molar mass of S8 = 32×8 = 256 g

so,

in one mole of S8 = 256 g of S8 = 6.022×10²³ molecules of S8 = 48.176×10²³ atoms of S

so,

in two moles of S8 = 48.176×10²³×2 = 96.352×10²³ = 9.6352×10²⁴ atoms of S
