C) moisture, falling air, and a lifting mechanism
Answer:
0.32×10⁻³ mol
Explanation:
Given data:
Number of atom of gold(II) chloride = 1.9×10²⁰ atoms
Number of moles = ?
Solution:
Avogadro number:
The given problem will solve by using 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 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
1.9×10²⁰ atoms × 1 mol / 6.022 × 10²³ atoms
0.32×10⁻³ mol
From the diagram, structure 1 would be the chloroplast and it represents the site of photosynthesis.
<h3>Plant cells</h3>
The image (see attached) is that of a plant cell and structure labeled 1 is the chloroplast.
The chloroplast of plant cells acts as the site of photosynthesis where inorganic materials are used to synthesize carbohydrates.
Plants generally serve as producers in food chains and thus, chloroplast helps sustain life.
