A student needs to make 0.855 L of a sodium bromide solution for an experiment. The concentration of the required solution is 0.
d1i1m1o1n [39]

Answer:

Explanation:

Molarity =  moles/liters of solution

moles    = molarity x Liters of solution

            =  0.350 m/L x 0.855 L

            =  0.299 mol

               mass = moles  x  molar mass    

            = 0.299 mol x 102.89 g/ms

            =  30.78 grams
