Answer: 3.00 molecules
Explanation:
Given that:
Mass of CO2 = 132.03 grams
Number of molecules of CO2 = ?
Molar mass of CO2 = ?
For the molar mass of CO2: Atomic mass of Carbon = 12; Oxygen = 16
= 12 + (16 x 2)
= 12 + 32 = 44g/mol
Apply the formula:
number of molecules = (mass in grams/molar mass)
N = (132.03 grams/44g/mol)
N = 3.00 molecules
Thus, there are 3.00 molecules of CO2 in 132.03 grams of CO2.

Answer:
I think these are it
Explanation:
The amount of current is the same at every point in a series circuit.
All of the parts of a series circuit—power source, wires, and devices—are connected along the same pathway
If one device in a series circuit burns out or is disconnected, the entire circuit is broken
The electrons have multiple pathways to travel.
Each time there is damage (break) in any one of the resistors the entire circuit will not function.
