What is the molar mass of Fe(CH2O2)3?
bija089 [108]

The Molar mass of Fe(CH_2O_2)^3 is 194g

<u>Explanation:</u>

Molecular mass of Fe = 56g

Molecular mass of C = 12g

Molecular mass of H = 1g

Molecular mass of O = 16g

Therefore, Molecular mass of Fe(CH_2O_2)^3

= 56+12\times3+6\times1+16\times6

= 56 + 36 + 6 + 96g

= 194g

So the Molar mass of Fe(CH_2O_2)^3 is 194g.
