A 0.286g sample of carbon dioxide, CO2, has a volume of 585mL and a pressure of 495mmHg . What is the temperature, in kelvins and degrees Celsius, of the gas?

Use PV = nRT and solve for T which will be in kelvin. Then

kelvin = 273 + C

n = number of mols = grams/molar mass

How would i use the grams in this equation though?

That's the line I wrote for

n = grams/molar mass

You must have n for PV = nRT

n = number mols CO2 and that is grams CO2/molar mass CO2

n = 0.286/44 = ?
