Explanation:
The given data is as follows.
Pressure of moist hydrogen gas = 1.018 atm
Pressure of water vapor =
= 0.0421 atm
Formula to calculate the pressure of dry hydrogen gas is as follows.
Pressure of
gas = 
Now, putting the given values into the above formula as follows.
Pressure of
gas = 
= 1.018 atm - 0.0421 atm
= 0.976 atm
Therefore, we can conclude that partial pressure of hydrogen gas in the given sample is 0.976 atm.
I'm pretty sure number 48 is C. Hope this helped :)

Answer:
The answer is
<h2>0.103 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 4 g
volume = 39.0 mL
The density is

We have the final answer as
<h3>0.103 g/mL</h3>
