Problem 12.002 the molar analysis of a gas mixture at 30°c, 2 bar is 40% n2, 50% co2, 10% ch4. determine
andreev551 [17]
The problem is incomplete. However, there can only be two probable questions for this problem. First, you can be asked the individual partial pressures of each gas. Second, you can be asked the volume occupied by each gas. I can answer both cases for you.

1.

Let's assume ideal gas.
Pressure for N₂: 2 bar*0.4 = 0.8 bar
Pressure for CO₂: 2 bar*0.5 = 1 bar
Pressure for CH₄: 2 bar*0.1 = 0.2 bar

2. For the volume, let's find the total volume first.

V = nRT/P = (1 mol)(8.314 J/mol-K)(30 +273 K)/(2 bar*10⁵ Pa/1 bar)
V = 0.0126 m³
Hence,
Volume for N₂: 0.0126 bar*0.4 = 0.00504 m³
Volume for CO₂: 0.0126*0.5 = 0.0063 m³
Volume for CH₄: 0.0126*0.1 = 0.00126 m³

What is the molarity if 2.00 liters containing 49.0 grams of sodium carbonate [Na2CO3)?
yKpoI14uk [10]

Answer: The molarity of solution is 0.231 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n}{V_s}

where,

n = moles of solute

V_s = volume of solution in L

Molar mass of Na_2CO_3 = 2\times 22.99+1\times 12.01+3\times 16.00=105.99

moles of Na_2CO_3 = \frac{\text {given mass}}{\text {Molar mass}}=\frac{49.0g}{105.99g/mol}=0.462mol

Now put all the given values in the formula of molality, we get

Molarity=\frac{0.462mol}{2.00L}

Molarity=0.231M

Therefore, the molarity of solution is 0.231 M

What is the number of protons in this carbon atom?
motikmotik

A - 12

The amount of protons in a specific element do not change, for if the protons change, then the element themselves change. Therefore, no matter what, if the question specifies the element (i.e. Carbon) then the amount of protons will remain the same as seen on the periodic table.

Hope this helps!
