The number of atoms in a 158.4 g sample of CO2 gas at STP is: 1.277 x 1025 atoms

2.167 x 1024 atoms

6.502 x 1024 atoms

6.651 x 1024 atoms

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

the answer is 303.15 or 303
