If a sample of 0.362 m lithium phosphate contains 0.284 g of lithium, what is the volume of the sample?
fenix001 [56]
From the periodic table:
mass of lithium = 6.941 grams
number of moles = mass / molar mass
number of moles of Li = 0.284 / 6.941 = 0.0409 moles

Molarity can be calculated using the following rule:
molarity = number of moles of solute / liters of solution
volume (in liters) = number of moles of solute / molarity
volume = 0.0409 / 0.362 = 0.1129 liters

By mistake, you added salt instead of sugar to the<br> oil. How can you remove the salt?
Ghella [55]

Explanation:

To remove the salt from the oil, I will add water to dissolve the salt from it.

Oil is an organic molecule that is non-polar

Salt is polar ionic compound

Salt will not dissolve in the oil.

  • Take the mixture.
  • Add water to it.
  • Water and oil are immiscible
  • Shake the new heterogeneous mixture vigorously.
  • leave to settle.
  • Oil will come on top of the water.
  • You can skim off the oil layer on top.
  • Then heat the water and salt solution.
  • This leaves the oil behind.

Among the following, which element has the lowest ionization energy? Question 2 options: Cs Na Cl I
marissa [1.9K]
The element with the lowest ionization energy is CESIUM, CS.
Ionization energy is the energy required to remove the most loosely bound electron in an atom of an element. The higher the number of shells in an atom of an element, the lower the ionization energy that will be required to remove the valence electron.
