An expensive vacuum system can achieve a pressure as low as 1.00 × 10 − 8 n / m 2 at 19.5 °c . how many atoms are there in a cubic centimeter at this pressure and temperature?

2475042

Explanation:

P = Pressure = [/tex]1\times 10^{-8}\ N/m^2[/tex]

V = Volume = 1 cm³

T = Temperature = 19.5 °C

R = Gas constant = 8.341 J/mol K

= Avogadro's number =

n = Amount of substance

From ideal gas law we have

Number of atoms is given by

The number of atoms in this vacuum is 2475042

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
