The pressure in a vacuum chamber is $1 0^{- 10}$ N/ $m^{2}$ at $2 7^{\circ}$ C. Find the number of molecules per $c m^{3}$ (nearest integer multiple of 100, give the number in hundreds).

Answer:

242.00

Solution:

$n = \frac{1 0 ^{- 10}}{1.38 \times 1 0 ^{- 23} \times 300} = 2.42 \times 1 0^{10}$ $m^{- 3} = 24155$ $c m^{- 3}$ , about 242 hundred.
