here is your answer...........

pls mark as brainliest

Answer 2

Answer:

1285.37

Explanation:

V 1=seven hundred ml

P 1=1 atm=760 mm Hg

T 1 =298 K          

V2=?

P2=four hundred mm Hg

T1 =288 K

Here variety of moles is constant.

∴ P1V1/T1=P2V2/T2 =760×seven hundred×288/298×four hundred

​

=1285.37 ml

∴ Volume occupied with the aid of using fueloline is 1285.37 ml.
