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 of the protein. how many zinc atoms does each carbonic anhydrase molecule contain

The mathematical expression for mass percent is given by:

Put the values,

mass of zinc =

= or 65.4 g

Now, number of moles of zinc  =

=

= 1.00 mole

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

Now, according to mole concept

molecules of enzyme consists of atoms of zinc

So, 1 molecule of enzyme contains  =

= 1 atom of zinc.

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

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
