What mass of iron (iii) nitrate will be in 129.8ml of a 0.3556 molar aq iron (iii) nitrate solution?

The mass of iron (III) nitrate is 11.16 g/mol

Explanation:

To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

We are given:

Molarity of solution = 0.3556 M

Molar mass of Iron (III) nitrate = 241.86 g/mol

Volume of solution = 129.8 mL

Putting values in above equation, we get:

Hence, the mass of iron (III) nitrate is 11.16 g/mol
