Astronomy -- pressures
The gas pressure of the photosphere changes substantially from its upper levels to its lower levels. Near the top of the photosphere and the temperature is about 4500 K and there are about 1.6x10^16 gas particles per cubic centimeter. In the middle the temperature is about 5800 K and there are about 1.0 x 10^17 gas particles per cubic centimeter. At the bottom of the photosphere the temperature is about 7000 K and there about about 1.5 x 10^17 gas particles per cubic centimeter. Using the ideal gas law (P = n(kb)T), compare the pressures of each of these layers and explain the reason for this trend.
Okay, how would you convert the number of gas particles per cubic centimeter into moles (for 'n' in the ideal gas law)? That's what I'm stuck on. Any help is appreciated!
