Question

Mass of carbon present in 0.2 mole of Fe4(Fe(CN)6)3is

Answer 1

Explanation:

There are 6 mol of carbon in 1 mol of K₄[Fe(CN)₆], so 0.5 mol contains 3 mol of carbon. The molar mass of carbon is 12.0 g/mol, so there are 36.0 g of carbon.

hope you understood.

mark me as BRAINLIEST PLS.

Answer 2

0.2 mole of Fe4(Fe(CN)6)3 has 43.2 g carbon.

Moles of Fe4(Fe(CN)6)3=0.2

Mass of Ag=107 g

Mass of Fe=56 g

Mass of C=12 g

Mass of N=14g.

Molar mass of Fe4(Fe(CN)6)3=860 g.

1 mole of Fe4(Fe(CN)6)3 contains 216 g of carbon.

0.2 mole of Fe4(Fe(CN)6)3 will contain=0.2x216 g carbon

=43.2 g.

43.2 g carbon is present in 0.2 mole of Fe4(Fe(CN)6)3.
