The mass of iron (III) oxide (Fe2O3) : 85.12 g
<h3>Further explanation</h3>
Given
3.20x10²³ formula units
Required
The mass
Solution
1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mol of Fe₂O₃ :
mass of Fe₂O₃ (MW=160 g/mol)
Answer:
Organ systems & their main functions
Explanation:
The chest bones Rib Cage & spine - protects the vital organs (heart, lung,liver) from injury & provides structural support for body.
Skin is the body's first line of defense & keeps the body warm. In case of any invading infection, fever - body temperature rise fights it.
Circulatory system (containing heart) & its body fluid blood - transports nutrients and oxygen to body cells
Endocrine system regulates growth, produces hormones - that target organs via bloodstream.
