changing the number of protons will change the atomic number, and if the atomic number is changed, it will become a different element. if you give oxygen 9 protons, it would no longer be oxygen, it would be fluoride.
Another M1V1=M2V2 <span>V1=1.0L </span> <span>M1=6.00M </span> <span>M2=0.500M </span> <span>V2=?? </span> <span>(6.00M)(1.0L)=(0.500M)V2 </span> <span>Solve for V2 you get 12L or 12000mL </span>
