Answer: My guess is D i hope this is right
Explanation:
Explanation:
that u know right .........................
M/V=D
16.52/2.26=D
Density=6.86 g/cm^3
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.
Answer:
c
Explanation:
kinetic energy can be calculated using the formula
=1/2*mass*velocity or speed ^2
