{"problem":"100 mL of a 0.250 M sodium fluoride (`\\( NaF \\)` ) solution is mixed with 100 mL of a 0.0250 M strontium nitrate (`\\( Sr(NO_3)_2 \\)`) solution. Determine the mass of dissolved strontium ions (`\\( Sr^{2+} \\)` ) in micrograms and rounded to two decimal places. The solubility product of strontium fluoride (`\\( SrF_2 \\)` ) is Ksp = `\\( 4.33 × 10^{-9} \\)` . Ignore the hydrolysis of the fluoride ion and consider the possible precipitation of strontium fluoride (`\\( SrF_2 \\)` ).\n\nAtomic Masses: Sr = 87.6, F = 19.0\n\nThink step by step and solve the problem below. At the end of your response, write your final answer on a new line starting with “FINAL ANSWER”. It should be an answer to the question such as providing a number, mathematical expression, formula, or entity name, without any extra commentary or providing multiple answer attempts.","subject":"chemistry"}
