recalling the standard formula p*v=k
where p=pressure,v=volume and k=constant
we have p1*v1=p2*v2 since temparature is contant we have
p1=0.180atm
v1=4.00L
p2=?
v2=9.30L
making p2 to be the subject of our formula we have
p2=%28p1%2Av1%29%2F%28v2%29
p2=(0.180*4.00)/9.30
p2=0.077
hence the new pressure=0.077atm
