How many moles of carbon are in 7.87x10^7 carbon atoms?

There are about 6.022*10^23 molecules in 1 mole of carbon

Lets say that the required number of moles will be x

1 mole —6.022*10^23

x moles—7.87*10^7

Cross multiply

x=7.87*10^7/6.022*10^23

Answer x=1.3*10^-16

where's the diagram?

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
