An expensive vacuum system can achieve a pressure as low as 1.83 ✕ 10−7 n/m2 at 28°c. how many atoms are there in a cubic centimeter at this pressure and temperature?

atoms

Explanation:

According to the ideal gas equation:

P = Pressure of the gas =    

V= Volume of the gas =       (1L=1000ml)

T= Temperature of the gas = 28°C = 301 K        

R= Gas constant = 0.0821 atmL/K mol

n=  moles of gas= ?

Number of atoms =

Thus there are atoms  in a cubic centimeter at this pressure and temperature.
