What pressure is exerted by 932.3 g of CH4 in a 0.560 L steel container at 136.2 K?
Roman55 [17]
Molar mass CH4 = 16.0 g/mol

* number of moles:

932.3 / 16 => 58.26875 moles

T = 136.2 K

V = 0.560 L

P = ?

R = 0.082

Use the clapeyron equation:

P x V = n x R x T

P x 0.560 =  58.26875 x 0.082 x 136.2

P x 0.560 = 650.76

P = 650.76 / 0.560

P = 1162.07 atm

Bingel [31]

The two elements that have the same properties as sodium are potassium  and rubidium .

<h3>What is periodic table?</h3>

The periodic table is an arrangement of the elements in order of increasing atomic number.

From the list, the two elements that have the same properties as sodium are potassium  and rubidium .

Proton has an atomic number of 20 and a mass number of 40. The number of electrons is the same as the number of protons. Given that the atomic number is the number of protons present, we have 20 electrons and 20 protons.

Number of neutrons = Mass number  - Number of protons

= 40 - 20 = 20 neutrons

Which is more concentrated, a solution containing 10g of NaCl in 100 g
Pavel [41]

Answer:

The answer is the solution containing the 90g of water.

Explanation:

Because both solutions have the same amount of the sodium chloride, the concentration would be the same if they both had the same amount of water.

Because the second solution has less water, there is more of the sodium chloride per each drop of water.

I hope this helps :)
