The total pressure of the mixture is 65.5 kPa.
According to Dalton's Law of Partial Pressure,
The partial pressure of gas = Mole fraction of gas × Total pressure
Total Pressure = Sum of all the gases partial pressures
The number of moles of methane is,
= 0.021 mols
The moles of methane are 0.021 mols.
The number of moles of the argon,
= 0.003 mols
The number of moles of argon is 0.003 mols.
The number of moles of nitrogen is,
= 0.010 mols
The number of moles of nitrogen is 0.010 mols.
The total number of moles is,
= 0.021 + 0.003 + 0.010
= 0.034 mols
= 0.29
= 65.5 kPa
Therefore, the total pressure of the mixture is 65.5 kPa.

<u>Answer:</u> The correct option is C) 1.68 mol/L
<u>Explanation:</u>
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
.....(1)
Given values:
Given mass of = 150 g
Molar mass of = 180 g/mol
Volume of the solution = 0.50 L
Putting values in equation 1, we get:
Hence, the correct option is C) 1.68 mol/L
