Answer:

n₂ =  6.8 mol

Explanation:

Given data:

Initial number of moles = 3.4 mol

Initial volume = 25 L

Number of moles = ?

Final volume = 50 L

Solution:

According to Avogadro law,

V₁/n₁  = V₂/n₂

Now we will put the values in formula.

25 L/3.4 mol = 50 L/ n₂

n₂ = 50 L× 3.4 mol/25 L

n₂ = 170 L.mol/25 L

n₂ =  6.8 mol
