Answer: The pressure of the He is 2.97 atm
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : 
=total pressure of gases = 6.50 atm
= partial pressure of Nitrogen = 1.23 atm
= partial pressure of oxygen = 2.3 atm
= partial pressure of Helium = ?
putting in the values we get:
The pressure of the He is 2.97 atm
Answer:
Nuclear fuel has a higher energy density than fossil fuel
Tempratures
1. -60 C = 213.15 K
2. 250 C= 523.15 K
3. 365 K = 91.85 C
4. 205 K = -68.15 C
Pressures
1. 22.0 inches Hg = 558.8 mm Hg
2. 3.4 atm = 2584 mm Hg
3. 680 mm Hg = 0.894737 atm
4. 785 mm Hg = 104.658 kPa

Answer: 40.5 mol
Explanation:
Since this is a double replacement reaction, the unbalanced equation is something like follows:
Balancing this equation,
From this equation, we can conclude that for every 3 moles of sodium hydroxide consumed, 1 mole of potassium phosphate is consumed.
This means the answer is 13.5(3)=<u>40.5 mol</u>
Higher value- mass number
Lower value- atomic number/ number of proton
