The masses of the objects and the distance between the two objects
Answer:
Partial pressure of hydrogen H₂ = 0.32 atm
Explanation:
Given:
Total pressure = 0.48 atm
Find:
Partial pressure of hydrogen
Computation:
Number of mole of H₂ = 1 / 2 = 0.5 moles
Number of mole of He = 1 / 4 = 0.25 moles
Total moles = 0.5 + 0.25 = 0.75
Partial pressure of hydrogen H₂ = [moles / total moles] Total pressure
Partial pressure of hydrogen H₂ = [0.50 / 0.75]0.48 atm
Partial pressure of hydrogen H₂ = 0.32 atm
This problem is providing us with the mass and density of a sample of liquid magnesium as 0.015 g and 1.738 g/cm³, respectively. Thus the volume, in microliters, of this same is required and found to be 8.63 μL according to the following calculations:
<h3>Density:</h3>
In science, density is defined as the degree of compactness of a substance and is calculated with:
Thus, given both the mass and density, we can solve for the volume as shown below:
By plugging in, we obtain the answer in cm³ first:
Then, we convert it to microliters as follows:
