1. Calculate the density of oxygen, O2, under each of the following conditions: STP 1.00 atm and 20.0 ∘C2. To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 3.6-L bulb, then filled it with the gas at 1.30 atm and 20.0 ∘C and weighed it again. The difference in mass was 5.5 g. Identify the gas.3. A sample of gas has an initial volume of 31.6L at a pressure of 1.1 atm. If the sample is compressed to a volume of 10.2 L, what will its pressure be?4. Use the molar volume of a gas at STP to calculate the density (in g/L) of carbon dioxide gas at STP.

We're no strangers to love

You know the rules and so do I

A full commitment's what I'm thinking of

You wouldn't get this from any other guy

I just wanna tell you how I'm feeling

Gotta make you understand

Never gonna give you up

Never gonna run around and desert you

Never gonna make you cry

Never gonna say goodbye

Never gonna tell a lie and hurt you

We've known each other for so long

Your heart's been aching but you're too shy to say it
