<Chapter 18 Item 7 7015 Pew Constants Periodic Table 1 The estimated average concentration of NO, inal in the United States in 2000 was 0.016 ppm Calculate the partial pressure of the NO, na sample of this ar when the atmospheric pressure is 786 torr (101 kPa). Express your answer using two significant figures Pos 1.2x10 torr Previous AB Correct ppmsade for parte per million. A concentration of 0.016 ppm of NO, 0.016 mol NO, per 1 x 10 molair XNO = 0.016 ppm NO 0.016 NO EXTV = 1.6 x 10 The mole fraction and the total atinonheric preure can then be used to call the parle pressure of NO, Hoy - XNO, P. 1.0*10 (755tor) Part How many molecules of NO, are present under these conditions at 1'n room that meet 11 x 15 x 5 Express your answer using two significant figures
