Question

Calculate the number of molecules of sulphur s8 present in 512 gram of solid sulphur. Given, atomic mass of S=32u ; Avagadro's Number = 6.022*10^23 per mole

Answer 1

let's calculate number of moles and we know that number of moles are given mass /molecular mass ..........given mass is 512gram and molecular mass of s8 is 32×8=256 .....so let's get moles with this as ..512/256=2.....so number of moles is two and one mole avagadros number of molecules so number of molecules are 2×6.023×10^23...I hope it helps ..in case any problem regarding this you can ask in comments. ..if it is helpfully please mark me brainliest and don't forget to follow me .so I can answer to you the first

◾◾here is your answer.

1 mole of solid sulphur (S8)

= 8 × 32g

= 256g

i.e., 256g of solid sulphur contains

= 6.022 × 10^23 molecules

Then, 512g of solid sulpur contains

(6.022×10^23 /256 )512 molecules

= 12 × 10^23 molecules (approx)
