Ответ:
3.43×10¹ mol
Explanation:
Given data:
Initial number of moles = 12.4 mol
Initial volume = 122.8 L
Final volume = 339.2 L
Final number of moles = ?
Solution:
The number of moles and volume are directly proportional to each other at same temperature and pressure.
Formula:
V₁/n₁ = V₂/n₂
Now we will put the values,
122.8 L/ 12.4 mol = 339.2 L / n₂
n₂ = 339.2 L× 12.4 mol / 122.8 L
n₂ = 4206.08 L.mol /122.8 L
n₂ = 34.3mol
In scientific notation:
3.43×10¹ mol
