What is the molarity of Br^- in each solution? b. 0.150 M CaBr₂

Video transcript

Hi everyone. So you ask coffee, the osmolarity of each given you have a nitrate ion 0.225 Molar of Magnesium Nitrate. Recall that osmolarity. It was the number of moles of ions divided by the leaders of solution. So for osmolarity this is equal to a number of ions, some similarity of the compound. So here we have magnesium nitrate and this is Aquarius and it's gonna associate into MG two plus a quiz In n. 0. 3 chris. Since we have two nitrate over here we can put a two in front of, you know, three minus. So in one mole of magnesium nitrate, We're going to produce two moles of nitrate ion since we have a two in front of nitrate ion. Over here, over the osmolarity we have to Time 0. smaller of magnesium nitrate. And this will give us 0.45 bowler of nitrite ions. Thanks for watching my video and I hope it was helpful
