this question every night to determine the volume. Well, 0.20 full of potassium sulfate solution that contains 57 grams of this substance. So here we've been given the polarity and we've been given the mass, you know, im to determine the volume you can rearrange the expression polarity equals mean first, right, That expression, so polarity equals more divided by you're going here would be nice to calculate the volume, right. So rearranging this expression here, rolling wench of equal to no invited by similarity, right? It seems we've been given the mass, you know that the mole is attained by their end in the mass over the moola mass. So with this expression, we have all the very we have everything we need to solve this question. So our volume, it's going to be given by the more developed them similarity. And we can determine the more by it right in the mask by the molar mass. We've been given the mass off 57 grams we have to do is calculate the Moloch missile potassium sulphate. You have to cope with the members of protection self it. Well, when I did company that I attend the value of 174 0.252 grams per mole. Now all we have to do is divide by the mill Ari, which has been given deserve point 20 Well, the leader. Right? So this we would attain a wrong name off 1.6 litres. That's the following over the protests himself. A solution that's gonna yield well that contains. And Maso 57 grams.
