Question

Calculate the number of molecules of sulphur (s8) parasite in 16 gram of side sulphur

Answer 1

first calculate molecular mass of so which is 32×8=256.....then calculate number of moles in 16gram of s8......moles=mass given /molecular mass which is 16/256 which is 1/16 .......so we get number of moles and we know one mole contains 6.023×10^23.....1/16(0.0625) moles would contain 0.0625×6.023×10^23 molecules by unitary method ......I hope you got your answer in case any problem you can ask in comments .and please don't forget to mark as brainliest and thanku

Answer 2

Number of moles= given mass/GMM

                             =16/16

                               =1mol

Number of molecules=avagadro number*1mol
