Question

please answer this question​

Answer 1

Answer:

420 mm of hg is the answwr

Answer 2

Explanation:

mole fraction of A = B

mole fraction A (Xa)= 1/2

mol fraction B Xb)= 1/2

as

mol fraction of (A+B)=1

as given

pure vp of A ( Pa)= 600 mm of hg

total Vp (Pt) =760 mm of hg

using formula

Pt= Pa Xa+ Pb Xb

760= 600/2+pb/2

pb= 460×2=920 mm of hg
