there is no available data about the density of such a solution, so how can i deduce it's molarity?

how can i calculate the number of moles of br2 in a solution of 10% (by weight) of br2 in dichloromethane?

maybe there is a way to calculate the average density of the two substances? or weighted mean of the densities or something like that?

True, as density of the solution grows linearly with the growth of mass concentration (fits the y = a + bx function).

hello!how can i calculate the number of moles of br2 in a solution of 10% (by mass) of br2 in dichloromethane?there is no available data about the density of such a solution, so how can i deduce it's molarity? what is the right way to solve it? thanks!
