QUESTION:
Interstellar space contains mostly hydrogen atoms at a concentration of about 1 \(\mathrm{atom} / \mathrm{cm}^{3}\). (a) Calculate the pressure of the H atoms. (b) Calculate the volume (in liters) that contains 1.0 g of H atoms. The temperature is 3 K.
ANSWER:Step 1 of 3
(a)
Here, we are going to calculate the pressure of the H atoms.
We know, 1.0 mol H = 6.022
1 cm3 =1.0 mL
1000 mL = 1.0 L
Therefore,
=
The pressure of H can be calculated from the ideal gas equation.
