Hi there. I am not looking for the answer to my homework, just help with understanding the problem so that I can figure out the answers.
Here is the problem: A neon sign is made of glass tubing whose inside diameter is 2.5 cm and whose length is 5.5 m. If the sign contains neon at a pressure of 1.75 torr at 31 C, how many grams of neon are in the sign?
