Molar concentration or Molority (M) is defined as the number of moles of rolute dissolve in one liter of solution. Therefore, Molar concentration =(" Number of malen of rolute ")/(" Litern of ") Given, 0.01 moles of the bare is disnalved in 500mL of water Then, number of mole of bare (rolute) =0.01 moles{:[" volume of the rolution "=500mL],[=(500)/(1000)L],[=0.5L]:}Therefore, molar concentration of the rolution =(0.01(mol))/(0.5(L ...
