Express your answer to two signifcant figures and inckude the appropriate units. 4.9 atm Submit Incorrect Try Again; 5 attempts remaining

Explanation / Answer

m = 35.1 g of CO2

T = 100 K, V = 3 L

Tnew = 298K

apply

PV = nRT

n = mass/MW

PV = mass/MW*RT

P =  mass/MW*RT/V

substitute vlaues

MW = 44 g/mol, R =0.082 Latm/molK

P =  35.1/44*8.314*298/3

P = 658.8089 atm
