Answer:

45.3 KPa

Explanation:

From the question given above, the following data were obtained:

Total pressure (Pₜ) = 101.3 KPa

Pressure of Hydrogen (Pₕ) = 56 KPa

Pressure of Oxygen (Pₒ) =?

The pressure of oxygen in the mixture can be obtained as follow:

Pₜ = Pₕ + Pₒ

101.3 = 56 + Pₒ

Collect like terms

101.3 – 56 = Pₒ

Pₒ = 45.3 KPa

Thus, the pressure of oxygen in the mixture is 45.3 KPa

To make a 0.500 M solution, one could take 0.500 moles of solute and add Group of answer choices enough solvent to make 1.00 kg
Fiesta28 [93]

<u>Answer:</u> The correct option is enough solvent to make 1.00 L of solution

<u>Explanation:</u>

A solution consists of solute and solvent. A solute is defined as the component present in a smaller proportion while the solvent is defined as the component that is present in a larger proportion.

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:

Molarity=\frac{Moles}{Volume} .......(1)

We are given:

Molarity of solution = 0.500 M

Moles of solute = 0.500 moles

Putting values in equation 1, we get:

0.500mol/L=\frac{0.500mol}{\text{Volume of solution}}\\\\\text{Volume of solution}=\frac{0.500mol}{0.500mol/L}=1.00L

Hence, the correct option is enough solvent to make 1.00 L of solution
