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

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

since electrons are negative the answer is neagtaive
