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.
