Answer:
The correct answer is option B.
Explanation:
The molecular formula of iron(II) acetate tetrahydrate.;
[tex]Fe(CH_3COO)_2.4H_2O[/tex]
Atomic mass of iron = 55.84 amu
Atomic mass of carbon = 12.01 g/mol
Atomic mass of oxygen = 16.00 amu
Atomic mass of hydrogen = 1.01 amu
Molecular mass of iron(II) acetate tetrahydrate:
[tex]1\times 55.84 amu+4\times 12.01 amu+14\times 1.01 amu+8\times 16.00amu[/tex]
[tex]=246.02 amu[/tex]
The closest option to 246.02 amu is 245.9 amu.
So, the correct answer is option B.
