Hey there!:
Molar mass CO2 = 44.01 g/mol
44.01 g CO2 ------------------- 6.02*10²² molecules CO2
88 g CO2 ------------------------ y
y = 88 * ( 6.02*10²² ) / 44.01
y = 5.29*10²⁵ / 44.01
y = 1.2 * 10²⁴ molecules of CO2
Answer A
Hope that helps!

Answer:
3) Ionic
Explanation:
The solid formed when a bond occurs between magnesium and oxygen is an ionic bond. This bond type occurs between a metal and non-metal.
- Magnesium is the metal
- Oxygen is the non - metal
- Due to the large electronegativity difference between the two species, the metal loses electrons which the non-metal oxygen gains
- They both complete their octet and electrostatic attraction leads to the formation of ionic bonds.
