3. Express barometric pressure in standard atmospheric pressure
4. Express volume of flask in cm3
5. Calculate density of vaporized unknown.

This appears that you want me to do your lab calculations for you. I'll be glad to help you through it if you explain what you don't understand. I can't believe you can't do ANY of it.
