Answer &Explanation:
From Avogadro's lawa equal volume of gas contain equal number of moles
V=N
Hence
13L=965
XL=3.2mol
Hint:as the question state is increase to iteans final mol was 3.2 but if it could state by it would mean initial moles plus adde moles ie 3.2mol)
Cross multiplication
The new volume will be
=(3.2mol×13L÷965mol)
=0.043L
