1. A gas syringe is connected through a delivery tube to a conical flask which is immersed in a beaker of boiling water. The water is being heated by a constant bunsen burner flame as shown in Fig. 1.1. The syringe is frictionless so the gas pressure within the system remains equal to the atmospheric pressure 1.02 × 10³ Pa. 

 Fig 1.1

The total volume of the conical flask and delivery tube is 325 cm³, and after settling in the boiling water the gas syringe has a volume of 30 cm³.

Calculate the total number of moles contained within the system.
