This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. E) The product of concentration and volume of the less concentrated solution equals the product of concentration and volume of the more concentrated solution. Assume that the volume of the final solution is 50.0 mL. AgBr is widely used in photographic films and is believed by some to have been used for making the Shroud of Turin. b$tA,d@,w4;Dh .%u@B/ $x@U0%L@bv.#rF*0
