I have a chemistry question on my homework that says
The density of a gas at 273K and 760mmHg(1atm) is 4.00g/l. What is its molar mass in g/mol?
Ive got it so far from Pmm=DRT to mm=(4.00g/L)(.0821Latm/molK)(273K)/1atm
The problem is i need to convert the 4.00 g/L to g/mol and im confused about doing this...ive gotten the 4.00L to 4000 mL and apparently i can convert mL to grams but im confused about this part. What do I do, or am I just doing this completely wrong? Please help!
