The mass spectrum of an organic compound shows the relative abundances of m to be 85.03% and m 1 to be 21.15%. assuming the peaks are caused by 12c and 13c isotopes, determine the number of carbon atoms in the compound. natural abundances: 12c is 98.93% and 13c is 1.07%

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night.  when he took it out, its new volume was 322 milliliters, but its pressure was the same.  if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is  kelvins.

Choose all the answers that apply. as ocean depth increases, temperature decreases temperature increases pressure increases pressure decreases salinity increases density increases
