MODULE 3 UNIT 3 Assignment Part A This assignment is to be sent to your instructor for evaluation. Solve the problems using Boyle’s law. Assume that the temperature is constant. Show all calculations. 1) A gas measuring 525 mL is collected at 104.66 kPa. What volume does this gas occupy at 99.33 kPa? Pi= 104.66kPa Pf= 99.33kPa Vi= 525mL Vf= ? Vf = Vi x Pi/Pf = Vf = 525mL x 104.66kPa/ 99.33kPa = 553.17 mL (3 marks) 2. The pressure on 6.0 L of a gas is 200 kPa. What will be the volume if the pressure is doubled, keeping the temperature constant? Pi= 200 Pf= 400 Vi= 6 Vf= ? Vf = Vi x Pi/Pf = Vf = 6 x 200/400 = 3.0 L (3 marks) 3. 2.00 L of a gas is at 740.0 mmHg pressure. What is its volume at 760
