The enzyme, carbonic anhydrase, is a large zinc-containing protein with a molar mass of 3.00 x10^4 g/mol. Zn is 0.218% by mass o
tia_tia [17]

The mathematical expression for mass percent is given by:

Mass percent = \frac{mass of the compound}{molar mass of the compound}\times 100

Put the values,

0.218 percent of zinc = \frac{mass of zinc}{3.00 \times 10^{4} g/mol}\times 100

mass of zinc = 0.218 \times (3\times 100) g

= 0.654 \times 100 g or 65.4 g

Now, number of moles of zinc  =\frac{given mass in g}{molar mass of zinc}

= \frac{65.4 g}{65.38 g/mol}

= 1.00 mole

Number of atoms of zinc is calculated by the Avogadro number.

Now, according to mole concept

6.022\times 10^{23} molecules of enzyme consists of 6.022\times 10^{23} atoms of zinc

So, 1 molecule of enzyme contains  =\frac{6.022\times 10^{23}atoms of zinc}{6.022\times 10^{23} }

= 1 atom of zinc.

Hence, every carbonic anhydrase molecule consists of 1 atom of zinc.
