If 12.4 mol of Ne gas occupies 122.8 L, how many mol of Ne would occupy 339.2 L under the same temperature and pressure? Record your answer in scientific notation using 3 significant figures.

Respuesta :

Neetoo

Answer:

3.43Ɨ10Ā¹ mol

Explanation:

Given data:

Initial number of Ā 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:

Vā‚/nā‚ Ā = Ā Vā‚‚/nā‚‚

Now we will put the values,

122.8 L/ 12.4 mol Ā = Ā 339.2 L / nā‚‚

nā‚‚ = 339.2 LƗ 12.4 mol Ā / 122.8 L

nā‚‚ = 4206.08 L.mol /122.8 L

nā‚‚ = 34.3mol

In scientific notation:

3.43Ɨ10Ā¹ mol
