a
2.5\(cm^3\)
b
15.5\(cm^3\)
c
18.7\(cm^3\)
d
21.4\(cm^3\)
e
72.5\(cm^3\)

Here is an explanation:
Following the easiest step as a jambite you don't need to Waste time on one question...........
Firstly list out all the........... This way...
VI=20cm^3
P1=700mhg
V2?
P2=750mhg.
Using the formular---------------
VIP1
-----------
V2P2
but you are to find the V2...
So the equation now becomes
V2= V1P1
--------
P2
V2= 20*700
-------------
750
i.e
V2=14000
----------
750
V2= 18.666667
you approximate
V2=18.7..
Hope this helps
