okay so i have no idea how to do anything in chapter 5 at all its about the nature of properties of solutions and my teacher cant help because shes too busy running around and i really need help okay
so when do i use the formula's how do i use them
and how do i get rid of the units and change them around
say there was a questions
asking what mass of magnesium bromide must be dissolved to make 1.50L of a solution with a brominde ion concentration of 0.30 mol/L ?
another questions would be
A sterling sliver ring has a mass of 12.0g and contains 11.1g of pure sliver . What is the percentage weight by weight concentration of sliver in the metal?
i know this is alot to ask but if anyone could help
it would be very very helpful in me actually learning this chapter and passing .
