By overlaying the residences of the casualties on a city map that showed sources of water, the pump on Broad Street appears to be clearly implicated in the transmission of the disease." While writing a report, a student uses this source for background information about data presentation le of excellence in data presentation comes from a study of the cholera outbreak in London in 1854.

Answer:
0.08097 grams of nitrate ions are there in the final solution.
Explanation:
Moles of cobalt(II) nitrate ,n=
Volume of the cobalt(II) nitrate solution, V = 100.0 mL = 0.1 L
Let the molarity of the solution be
A students then takes 4 .00 mL of solution and dilute it to 275 ml.
(molarity after dilution)
(after dilution)
Molarity of the of solution after dilution is 0.002375 M.
1 mol of cobalt(II) nitrate gives 2 moles of nitrate ions. Then 0.002375 M solution of cobalt (II) nitrate will give:
Moles of nitrate ions = n
Volume of the solution = 275 mL = 0.275 L
Molarity of the nitrate ions =
n = 0.001306 mol
Mass of 0.001306 moles of nitrate ions:
0.001306 mol × 62 g/mol= 0.08097 g
0.08097 grams of nitrate ions are there in the final solution.
