C. It has mass and volume

Explanation:

Every atom of an element has mass and volume. Mass is the amount of substance it contains this is usually a function of their subatomic particles.

The bulk of the mass of an atom is concentrated in the nucleus where we have protons and neutrons. Electrons do not really add much to the mass of an atom.

Atoms also have specific volume.

  • The reason for our selection is that atoms are the smallest particle of matter.
  • Matter is anything that has weight and occupies space.
  • Since it is matter, it must have specific weight and volume

How many formula units make up 12.8 g of magnesium chloride ( MgCl2)? Express the number of formula units numerically.
Advocard [28]

Answer:

For 12.8 g there 0.807 × 10³ formula units.

Explanation:

Given data:

Mass of MgCl₂ = 12.8 g

Formula units for given mass = ?

Solution:

First of all we will calculate the number of moles.

Number of moles = mass/molar masss

Number of moles = 12.8 g/ 95.211 g/mol

Number of moles = 0.134 mol

According to the Avogadro number,

one moles = 6.022 × 10³ formula units

For 0.134 mol,

0.134 × 6.022 × 10³ formula units

0.807 × 10³ formula units

For 12.8 g there 0.807 × 10³ formula units.
