Answer:
2.71×10²⁴ particles
Explanation:
Applying Avogadro's constant
Avogadro's constant states that, The number of specified particles contained in a mole of a substance is equal to 6.02×10²³.
From the question,
If one mole of chlorine contains a particle of 6.02×10²³,
Therefore,
4.5 moles of chlorine will contain a particle of (4.5× 6.02×10²³)
⇒ 27.09×10²³
Hence the number of particle contained in 4.5 moles of chlorine ≈ 2.71×10²⁴ particles

Explanation:
In order to find whether it will sink or float in water we must first find the density of the object
The density of a substance can be found by using the formula
From the question
mass = 18 g
volume = 9 cm³
So we have
We have the density as 2.0 g/cm³
The object will sink in water since it's density is greater than that of water which is 1.0 g/cm³
