Atomic mass C = 12.0107
Atomic mass O= 15.9994
Calculate the molecular mass of the CO2
12.0107 + (2 x 15.9994) = 44.0095
Multiply the mass of CO2 by the conversion factor that relate the O mass to the molecular mass of CO2 to find the mass of O in the 71.89g of CO2
71.89 g CO2 x (2 x 15.9994) / 44.0095 =
52.2703900748702
52.27 g O
Answer:
D. protons that is the answer
<span>Phosphorus trifluoride (formula PF3), is a colorless and odorless gas. is similar to carbon monoxide and this is very toxic according to my research. hope this helps.</span>
The answer is (E). protons.
The atomic number of an atom is equal to the number of protons in the nucleus.
I hope this helped.
