The mass density of diamond (a crystalline form of carbon) is 3500 kg/m3. How many carbon atoms per cm3 are there? 

A mass spectrometer is designed to separate atoms of carbon todetermine the fraction of different isotopes. (Isotopes of anelement, as we will see in chapter 20, have the same atomic numberbut different atomic mass, due to different numbers of neutrons.)There are three main isotopes of carbon, with the following atomicmasses:

12C 1.99x10-26kg

13C 2.16x10-26kg

14C 2.33x10-26kg

The atoms of carbon are singly ionized and enter a massspectrometer with magnetic field strength B=0.200T at a speed of1.50x105m/s. The ions move along a semicircular path andexit through an exit slit. How far from the entrance will the beamsof the different isotope ions end up?

Carbon absorbs energy at a wavelength of 150 nm. The total amount of energy emitted by a carbon sample is 1.98 × 105 J. How many carbon atoms present in the sample, assuming that each atom emits one photon?
