Answer:

the density of silver is calculated as

Data;

- edge length = 408.7pm
- atomic mass = 107.8682
- Avogadro's number = 6.022*10^23 atoms /mol

The density of a substance is the ratio between the mass to the volume of that substance. In this case, the density of silver is calculated as

Let's substitute the values into the formula

From the calculations above, the density of silver is calculated as

Answer:

The density of silver can be calculated by using the following formula:

Here, m is mass and V is volume.

To calculate density, mass of silver needs to be calculated first.

In FCC, the number of Ag atoms in a unit cell will be 4, atomic mass of Ag is 107.87 g/mol and number of atoms in 1 mol are atoms, thus, mass can be calculated as follows:

.

Now, volume can be calculated as follows:

First convert pm to cm:

Thus,

Putting the value to calculate volume,

Now, calculate density as follows:

Therefore, density of silver is .

Once primers bind,what occurs next

Once the primers bind to the DNA, the hotness is then elevated once again to 72 degrees Celsius. At this temperature, the DNA polymerase is capable to perform by adding the appropriate nucleotides against the primer, and, consequently, prolonging the primer.
