Question : Calculate the molermass of the following substances a) Ethy

1.	Question : Calculate the molermass of the following substances a) Ethyne, C_(2)H_(2) b) Sulphur moelcular, S_(8) c) Ohosphorus molecule - P_(4) d) Nitric acid , HNO_(3)
Answer» Solution :a) Ethyne, `C_(2)H_(2)`. Molar MASS of ethyne, `C_(2)H_(2)=2xx12+2xx1=26g` b) Sulphur molecule , `S_(8)` Molar mass of Sulphur molecule, `S_(8)=8xx32=256g` C)Phosphorus molecule, `P_(4)` Molar mass of phosphorus molecule, `P_(4)=4xx31=124g` d) HYDROCHLORIC acid, HCl Molar Mass of hydrochloric acid HCl `=1+35.5=36.5` g e) Nitric acid, `HNO_(3)` Molar mass of Nitric acid, `HNO_(3)=1+14+3xx16=63`g
