Pycnometry

Question 1

What are the steps to liquid pycnometry?

Answer 1

1. weigh empty pycnometer: W1
2. weigh pycnometer with dry particles: W2
3. weigh pycnometer with particles filled with liquid: W3
4. weigh pycnometer with liquid only: W4

Question 2

What is the theoretical/true density given by liquid pycnometry?

Answer 2

~ p = [(W2-W1)/(W4-W1)-(W3-W2)]

Question 3

What is the weight of fluid in volume V?

Answer 3

~ W4-W1

Question 4

What is the weight of fluid in volume V when some volume is taken up by particles?

Answer 4

~ W3-W2
