• URGENT! Dear experts, Pls explain the question with proper solution. Thank you.
  
• at 25 degree celsius and 0.993 bar, 135 ml of a gas is collected over water. if the gas weighs 0.16g and the aqueous tension at 25 degree celsius , is 0.0317. calculate the molar mass of the gas.
• The volume of the gas at 0'C and 700mm pressure is 760 CC.The no.of molecules present in this volume is ?  
• 3rd?
