Answer to Question #141360 in General Chemistry for yara
Question #141360
280 grams of CaO is dissolved in enough water to make 10 L of solution.
Expert's answer
I guess your question is what the concentration of CaO in the solution
Molar mass of CaO = 40+16= 56g/mol
Mole of CaO dissolved = mass / molar mass = 280/56= 5 moles
Concentration = mole/ volume = 5mol/10L = 0.5mol/L
