To calculate the molar mass of fungal laccase, we need to divide the mass of 4 Cu atoms by the percent composition of Cu in fungal laccase.

Given that fungal laccase is 0.390% Cu by mass, this means that for every 100 grams of fungal laccase, there are 0.390 grams of Cu.

So, the mass of Cu in fungal laccase can be calculated using the following equation:

Mass of Cu = (0.390/100) × Molar mass of fungal laccase

We know that a fungal laccase molecule contains 4 Cu atoms. Since the molar mass is the mass of one mole of a substance, we can calculate the molar mass of fungal laccase using the following equation:

Molar mass of fungal laccase = Mass of Cu / 4

Substituting the values, we can calculate the molar mass:

Molar mass of fungal laccase = (0.390 / 100) × Molar mass of fungal laccase / 4

To solve for the molar mass of fungal laccase, we can rearrange the equation to isolate the molar mass:

Molar mass of fungal laccase = (0.390 / 100) × 4 / (0.390 / 100)

Simplifying the equation, we get:

Molar mass of fungal laccase = 4

Therefore, the molar mass of fungal laccase is 4 g/mol.
