Answer 1

sus): initial ditate V=505 ml. T= -15+ 273·15=258.15k after breath in V2 = ? T= 37+ 273·15=310.15k if Presedwee and moles of gas is constant. so. Y = va a T Ta V2 = V XT2=505 ml x 3100 15k 258.15K final volume of gas = 606.72 me 2) Fai Eq. of Nat in 1.42 solution - Normality x volume = 150m Eq/X 1044 = 210 mEq. malus - 210X10* £9 x 1 mal Teq = 0.21 mal Thank you
