Fungal laccase, a blue protein found in wood-rotting fungi, is 0.390% Cu by mass. 1f a fungal laccase molecule contains four copper atoms, what is the molar mass of fungal laccase?
Interpretation Introduction
Interpretation: The mass percentage of copper in fungal laccase is given. By using this value, the molar mass of fungal laccase is to be calculated.
Concept introduction: Molar mass of a substance is defined as the mass of the substance in gram of one mole of that compound.
The molar mass of any compound can be calculated by adding of atomic weight of individual atoms present in it.
To determine: The molar mass of fungal laccase.
Explanation of Solution
Given
The percentage composition of copper
The number of copper atoms in fungal laccase is 4.
The atomic weight of copper
Formula
The molar mass of compound is calculated as,
