Answer:
Ans space is space left parenthesis straight b right parenthesis space 0.33 space and space 0.52

Helium space is space initially space 200 space ml space at space 0.66 space atm space but space finally space it space is space placed space in space straight a space vessel space of space volume space 400 space ml space
straight P subscript 1 straight V subscript 1 equals straight P subscript 2 straight V subscript 2

0.66 cross times 200 equals straight P subscript 2 cross times 400

space space space space space space space space space space space space straight P subscript 2 space space space equals space 0.33 space atm

Now space initially space straight O subscript 2 space is space present space at space 0.52 space atm space 400 ml space then space space placed space in space straight a space vessel space of space volume space 400 space ml space

straight P subscript 1 straight V subscript 1 equals straight P subscript 2 straight V subscript 2

0.52 cross times 400 equals straight P subscript 2 cross times 400
space space space space space space space space space space space space straight P subscript 2 space space equals space 0.52 space atm
