Because oxygen is more electronegative than hydrogen, the water molecule is polar.
Your answer would be,
Formula: Molarity (M) = Number of moles of solute/Solutions volume Liters
0.009(50) = .45 gm dissolved in 50 ml H2o
= 0.20(50) = 10 gm
Hope that helps!!!
When magnesium ions and chloride ions form a compound the chemical formula would be MgCl2 which means that for every 1 atom of Mg+ there would be 2 atoms of Cl- bonded. This would be proportional to units of moles.
Moles Cl- = 0.25 mol Mg2+ ( 2 mol Cl - / 1 mol Mg2+) = 0.50 mol Cl- would be needed
The pH scale is a measurement system that indicates the concentration of H+ ions in a particular solution.
