I tried to answer it now I'm stuck in the same hole -_-
Answer: A pressure of 0.681 atm would be exerted by 0.023 grams of oxygen
if it occupies 31.6 mL at
.
Explanation:
Given : Mass of oxygen = 0.023 g
Volume = 31.6 mL
Convert mL into L as follows.

Temperature = 
As molar mass of
is 32 g/mol. Hence, the number of moles of
are calculated as follows.

Using the ideal gas equation calculate the pressure exerted by given gas as follows.
PV = nRT
where,
P = pressure
V = volume
n = number of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the value into above formula as follows.

Thus, we can conclude that a pressure of 0.681 atm would be exerted by 0.023 grams of oxygen
if it occupies 31.6 mL at
.
I think the number of protons in the nucleus the number of valence electrons atomic mass...
Answer:
<h2>0.93 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 37.2 g
volume = 40 mL
We have

We have the final answer as
<h3>0.93 g/mL</h3>
Hope this helps you
