Consider three gases: Ar, SF6, and Cl2. If 50.0 grams of these gases are placed in each of three identical containers, which con
adoni [48]
The ideal gas law:
pV=nRT \Rightarrow p=\frac{nRT}{V}
p - pressure, n - number of moles, R - the gas constant, T - temperature, V - volume

The volume and temperature of all three containers are the same, so the pressure depends on the number of moles. The greater the number of moles, the higher the pressure.
The mass of gases is 50 g.

Ar \\
M \approx 39.948 \ \frac{g}{mol} \\
n=\frac{50 \ g}{39.948 \ \frac{g}{mol}} \approx  1.25 \ mol \\ \\
SF_6 \\
M \approx 146.06 \ \frac{g}{mol} \\
n=\frac{50 \ g}{146.06 \ \frac{g}{mol}} \approx 0.34 \ mol \\ \\
Cl_2 \\
M=70.9 \ \frac{g}{mol} \\
n=\frac{50 \ g}{70.9 \ \frac{g}{mol}} \approx 0.71 \ mol

The greatest number of moles is in the container with Ar, so there is the highest pressure.

An isotope contains 26 protons, 24 electrons and 32 neutrons what is the identity of the isotope?
Tema [17]

Hey there!

26 protons + 32 neutrons = 58

26 protons means the element is iron, which is Fe.

Find the charge by finding the difference between protons and electrons.

26 - 24 = 2 (+)

We have 58, Fe, and 2+.

Your answer is 58Fe2+.

Hope this helps!
