- An experiment shows that a 245mL gas sample has a mass of 0.436g at a pressure of 757 mmHg and a temperature of 29C. What is the molar mass of the gas?
- 0.4g of a gas has a volume of 227cm^3 at 27°C and at a pressure of 100kPa. Calculate the relative molecular mass of the gas (R=8.31 J/kmol)?
- We have a lab assignment that we haven't had a lecture on yet. It's the Pv=nRT. I had to graph 50 plus atm measurements & K temps on Excel. We are supposed to answer "# of moles of the gas in the 250mL sealed flask." I do not know where to go next?
