Solution :
The smallest integer value represents the smaller number of protons.
In this case, in the given values, the smallest numbers are 8 mm and 9 mm, so both contains 1H each. Then next highest value is 17 mm, which contains 1H more. Thus 17 mm contains 2H each. Then the next highest is 25 mm and 26 mm which contains 3M each and so on.
Thus the tables is :

26 mm 3
17 mm 2
25 mm 3
26 mm 3
9 mm 1

Answer:
40 g/mol, Argon
Explanation:
We can find the number of moles of the gas by using the equation of state for an ideal gas:
![pV=nRT](https://tex.z-dn.net/?f=pV%3DnRT)
where
is the pressure of the gas at STP
is the volume of the gas
n is the number of moles
is the gas constant
is the absolute temperature of the gas at STP
Solving for n, we find:
![n=\frac{pV}{RT}=\frac{(101,300)(2.96\cdot 10^{-3})}{(8.314)(273)}=0.132 mol](https://tex.z-dn.net/?f=n%3D%5Cfrac%7BpV%7D%7BRT%7D%3D%5Cfrac%7B%28101%2C300%29%282.96%5Ccdot%2010%5E%7B-3%7D%29%7D%7B%288.314%29%28273%29%7D%3D0.132%20mol)
Now we can find the molar mass of the gas, which is given by
![M_m=\frac{m}{n}](https://tex.z-dn.net/?f=M_m%3D%5Cfrac%7Bm%7D%7Bn%7D)
where
m = 5.28 g is the mass of the gas
n = 0.132 mol is the number of moles
Substituting,
![M_m=\frac{5.28}{0.132}=40 g/mol](https://tex.z-dn.net/?f=M_m%3D%5Cfrac%7B5.28%7D%7B0.132%7D%3D40%20g%2Fmol)
So, the gas in this problem is Argon, which has a molar mass of 40 g/mol.
Answer:
Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity
AlBr3(aq) is an ionic compound which will have the releasing of 3 Br⁻ ions ions in water for every molecule of AlBr3 that dissolves.
AlBr3(s) --> Al+(aq) + 3 Br⁻(aq)
[Br⁻] = 0.16 mol AlBr3/1L × 3 mol Br⁻ / 1 mol AlBr3 = 0.48 M
The answer to this question is [Br⁻] = 0.48 M
