Question 2 (1 point)

Which of the following best describes how to prepare a 25.0 mL of a stock solution of nickel (II) nitrate at a concentration of approximately 0.034 M.

Question 2 options:

	weigh out the exact amount of grams of nickel(II) nitrate hexahydrate using a medium-sized weigh boat, funnel it into a 25 mL volumetric flask, fill the flask with distilled water until you reach the volumetric mark on the flask.
	weigh out the exact amount of grams of nickel(II) nitrate hexahydrate using a medium-sized weigh boat, funnel it into a 25 mL volumetric flask, fill the flask about 1/2 way with distilled water to dissolve the solid, swirl the flask and then fill up the flask with more distilled water until you reach the volumetric mark on the flask.
