Answer:
Pressure is often defined as a measure of force applied on an area, or over a unit area.
Explanation:
The Ksp of cobalt(II) hydroxide is equal to [OH-]2[Co2+]=5.92*10-15. And [OH-]=2[Co2+]=2*[Co(OH)2](dissolved). So the molar solubility of this compound is 1.14*10-5 M.
I believe it’s discarded because Moseley rearranged the elements by the number of protons is instead of atomic weight like Mendeleev did

Answer:
The correct answer is option (1).
Explanation:
Mass of the sample = 5.5 g
Percentage of carbon in sample = 35 %
Percentage of oxygen in sample = 100% - 35%
Mass of carbon in a sample: (35%) of 5.5 g
Mass of oxygen in a sample: (100%-35%) of 5.5 g
