Question

A gas of 3.4 moles occupies of a volume of 25 Liters. How many moles will occupy 50 Liters?

Answer 1

n₂ = 6.8 mol

Step-by-step 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
