How many atoms of fe are in 45.00 grams of fe?

4.852*10^23

Explanation:

Use dimensional analysis.

First turn grams to moles using the molar mass of Fe (you can't convert to atoms from grams).

Then turn moles into atoms using Avogadro's constant.

45g Fe/55.85 g/mol Fe*6.022*10^23 atoms Fe

it is called acid bonding

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.
