Question

the mass of carbon present in 0.5 moles of k4 fe(cn)6

Answer 1

hey friend !!!!!?

your answer is option "d"

I think it is

K4[Fe(CN)]6 (Potassium ferrocyanide)

Molar mass of Given compound is 368.35 g/mol.

molar mass means mass of 1 mole of substances.

1 mole Potassium ferrocyanide contains 12 x 6 grams of carbon.

0.5 moles contains 12 x 3 = 36 grams of carbon.


I think my answer is capable to clear your confusion..

Answer 2

Yup, option d) is right
Because mass of carbon = molar mass of c in k4fe(CN6) multiple by no of moles of carbon
Therefore 36 g is the ans
