Question

Calculate the molar mass of the complex $\left[Fe\right(H_{2}O{)}_{5}NO]S{O}_4$.

• A. 272 g/mol
• B. 372 g/mol
• C. 250 g/mol
• D. 350 g/mol

Answer 1

The correct option is A 272 g/mol

The molar mass of the complex $\left[Fe\right(H_{2}O{)}_{5}NO]S{O}_4$ is equal to the sum of molar mass of individual components.
$=(56+10\times 1+10\times 16+14+32)g/mol$
$=272g/mol$
