How many atoms of mg are present in 97.22 grams of mg? 6.022 × 1023 2.408 × 1024 4.818 × 1024 5.855 × 1025

Second option

Explanation:

Number of atoms = Number of moles x Avogadro's Number

So first we need to find the number of moles in 97.22 grams of Mg.

Atomic Mass of Mg = 24

Number of moles = n = Given Mass / Atomic Mass

n = 97.22/24 = 4.05

Now we can calculate the Number of Mg atoms in 97.22 .

Number of atoms =

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

they are both synthetic elements
