Fungal laccase, a blue protein found in wood-rotting fungi, is 0.390% cu by mass. if a fungal laccase molecule contains four copper atoms, what is the molar mass of fungal laccase?

65,179.487 g/mol is the molar mass of fungal laccase.

Explanation:

Percentage of copper in Fungal laccase = 0.390

Molar mass of fungal laccase = M

Number of copper atom in 1 fungal laccase molecule = 4

Atomic mass of copper = 63.55 g/mol

Percentage of an element in a compound:

Percentage of copper:

M = 65,179.487 g/mol

65,179.487 g/mol is the molar mass of fungal laccase.
