Answer:
8.87 × 10⁻⁷ grams
Explanation:
Moles = No. of Particles / 6.022 × 10²³ Particles/mol
Moles = 4.95 × 10¹⁵ atoms / 6.022 × 10²³ atoms/mol
Moles = 8.22 × 10⁻⁹ mol
Also,
Mass = Moles × M.Mass
Mass = 8.22 × 10⁻⁹ mol × 107.87 g/mol
Mass = 8.87 × 10⁻⁷ grams
Answer:
Global warming is expected to cause changes in the amount of cloud cover, and the height and thickness of these clouds in the future, shifting the balance between the parasol and blanket effects of clouds. The knock-on effect this will have on temperature is known as cloud feedback

Here, Number of atoms = 0.46 * 6.23 * 10^23 [ Avogadro's number ]
= 2.77 * 10^23
In short, Your Answer would be Option B
Hope this helps!
Explanation:
It is the motion of particles that creates a form of energy called heat (or thermal) energy that is present in all matter. Tiny particles in solids, liquids and gases are always in motion. It is the motion of particles that creates a form of energy called thermal (heat) energy that is present in all matter.
