A student dissolved 5.00 g of Co(NO3)2 in enough water to make 100. mL of stock solution. He took 4.00 mL of the stock solution and then diluted it with water to give 275. mL of a final solution. How many grams of NO3- ion are there in the final solution? A) 0.0 247 g B) 0.0 493 g C) 0.0 678 g D) 0. 136 g E. 0.475 g 4

Use the References to access important values if needed for this question. A student weighs out a 6.27 g sample of AlBr3, transfers it to a 100. mL volumetric flask, adds enough water to dissolve it and then adds water to the 100. mL tick mark. What is the molarity of aluminum bromide in the resulting solution? Molarity M %3D
