Sodium<span> has one naturally occurring </span>isotope<span>. The </span>nucleus<span> of this isotope contains 11 </span>protons<span> and 12 </span>neutrons<span> and is not radioactive. There are 18 other known isotopes of sodium. All are radioactive. Sodium-22, sodium's most stable radioactive isotope, has a </span>half-life<span> of 2.6 year</span>
440 hertz = 440/seconds
1/440 seconds = period of the sound wave.
so Answer is 2.2727272* 10^-3 second or 1/440 seconds
2 moles of NO3 contains 6 moles of O
