Explanation:
Relation between total pressure and mole fraction is as follows.

where,
= partial pressure of gas 1
= mole fraction of gas 1
= total pressure of the gases
Also, it is known that
= 1
or, 
It is given that total pressure of gas mixture is 0.51 atm and partial pressure of helium is 0.32 atm.
Hence, calculate the mole fraction of helium gas present in the given mixture as follows.

0.32 atm = 
= 0.63
As,
= 1
so, 
= 1 - 0.63
= 0.37
Hence, calculate the partial pressure of Ne as follows.


0.3084 atm = 

= 0.834 atm
Thus, we can conclude that the partial pressure of the Ne in the mixture is 0.834 atm.
Answer: 26.25 miles per gallon
Explanation: first odometer reading = 65290
Second odometer reading = 65500
Difference in odometer reading = second reading - first reading
= 65500 - 65290 = 210 miles.
If it took 8 gallons to fill his tank, it means
8 gallons will get him 210 miles, therefore 1 gallon will get 210 miles/8gallons = 26.25miles/gallon. Hence he is getting 26.25miles/gallon.
Answer:
0.6941 mg
Explanation:
First we <u>calculate how many LiNO₃ moles there are</u>, using the <em>given concentration and volume</em>:
- 1.0 mL * 0.10 M = 0.10 mmol LiNO₃
As 1 mol of LiNO₃ contains 1 mol of Li,<em> in the problem solution there are 0.10 mmol of Li</em> (the only metallic ion present).
Now we<u> convert Li milimoles into miligrams</u>, using its <em>atomic mass</em>:
- 0.10 mmol Li * 6.941 mg/mmol = 0.6941 mg
Answer:
25mL
