Answer:
The correct answer is option B.
Explanation:
The molecular formula of iron(II) acetate tetrahydrate.;
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:
The closest option to 246.02 amu is 245.9 amu.
So, the correct answer is option B.
Aluminum has a molar mass of 27. So one mole of aluminum is 27grams
