How do I figure out what element is it describibg if I am given the temperature the pressure and the g/L.

Answer 1

Is this a gas? Use PV = nRT and calculate molar mass.
First calculate n = number mols (use a 1 L volume).
Then mols = grams/molar mass. You will have grams and mols and that leaves just molar mass. Then look up the molar mass (atomic mass) from the periodic table. If it isn't a gas you need to supply more details.

Answer 2

I do not know if it is a gas it just says to find what element is it and I am only given 1000 celsius, 10 torr, and the density of .0029 g/L.

Answer 3

Let's just think about it for a minute. At 1000 Celsius, won't most anything be a gas? Not iron, and that kind of metal. I think is must be a gas, otherwise, there would be no reason to give us a T and a pressure. The answer I worked out seems to be plausible.
