Answer:
0.5 mol
Explanation:
Given data:
Number of atoms of He = 3.01 ×10²³
Number of moles = ?
Solution:
Avogadro number:
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.02 × 10²³ is called Avogadro number.
1 mole = 6.02 × 10²³ atoms
3.01 ×10²³ atoms × 1 mol / 6.02 × 10²³ atoms
0.5 mol
Answer:
10 °C
Explanation:
Hello,
Based on the atmospheric conditions, unsaturated air cools at a constant rate of 10 °C per 1000 meters of ascent, meanwhile saturated air cools at a slower rate above the lifting condensation level due to the release of latent heat for the wet adiabatic rate.
Best regards.
