Solutions
Expert Solution
weight of NH4Cl = 21.5g
gram molecular weight of NH4Cl = 53.491g/mole
volume of solution = 500ml
molarity = W*1000/G.M.Wt * volume of solution in ml
= 21.5*1000/53.491*500 = 0.804M
NH4Cl(aq) -----------> NH4^+(aq) + Cl^-
0.804M 0.804M 0.804M
concentration of NH4^+ = 0.804M
concentration of Cl^- = 0.804M

A student placed 14.5g of glucose (C6H12O6) in a volumetric
flask, added enough water to dissolve the glucose by swirling, then
carefully added additional water until the 100mL mark on the flask
was reached. The flask was then shaken until the solution was
uniform. A 40mL sample of this glucose solution was diluted to
0.500L. How many grams of glucose are in 100mL of the final
solution?
