Homework Statement
What mass of aluminum nitrate should be dissolved in 225 ml of water to make a solute with a total nitrate concentration of 0.866 M ?
Homework Equations
M = n/L
The Attempt at a Solution
So, i keep getting the wrong answer. THe answer is suppose to be 13.8 g but i get a different number
:
.226 L * (0.866 mols/L) = 0.19485 mols needed
Nitrate molar mass is just 16*3 + 14 + 26.98= 88.98 g/mol
0.19485 * 62 = 17.33 grams of Aluminum nitrate
