A similar question has been answered, see above link.

P =?

V = 150.0 ml = 0.150 L

n = moles = 610 g N2 x 1 mol/28 g = 21.8 moles

R = gas constant = 0.0821 L-atm/K-mole

T = temp = 0ºC + 273 = 273K

PV = nRT

P = nRT/V = (21.8)(0.0821)(273)/0.15

P = 3257 atm = 3260 atm (to 3 significant figures)
