Answer:

0.0659M

Explanation:

...5,15g  of Fe(NO₃)₃ is dissolved...

Molar concentration is the amount of moles presents in 1L of solution. To solve this question we need to find the moles of iron nitrate, Fe(NO₃)₃ present in the 323mL of solution:

Moles Fe(NO₃)₃ -Molar mass 241.86g/mol-:

5.15g Fe(NO₃)₃ * (1mol / 241.86g) = 0.0213moles Fe(NO₃)₃

And molarity is:

0.0213moles Fe(NO₃)₃ / 0.323L = 0.0659M
