Answer:

Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. ... Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.

I hope it's helpful!

A lead atom has a mass of 3.14 x 10 to the negative 22nd g.How

frozen [14]

Explanation:

The given data is as follows.

Mass of a lead atom = $3.14 \times 10^{-22}$

Volume = 2.00 $cm^{3}$

Density = 11.3 $g/cm^{3}$

As it is mentioned that 1 cubic centimeter contains 11.3 grams of lead.

So, in 2 cubic centimeter there will be $2 \times 11.3 g = 22.6 g$ of lead atoms.

One lead atom has a mass of $3.14 \times 10^{-22}$ . Therefore, number of atoms present in 22.6 g of lead will be as follows.

$\frac{22.6 g}{3.14 \times 10^{-22}}$

= $7.197 \times 10^{22} atoms$

Thus, we can conclude that there are $7.197 \times 10^{22} atoms$ of lead are present.

Answer:

<u><em>294.307 g/mol</em></u>

Explanation:

The first question for this statment is:

<em>Calculate the gram-formula-mass of aspartame. </em>

<em />

<h2>Solution</h2>

The chemical formula is:

$C_{14}H_{18}N_2O_5 .$

The <em>gram-formula-mass </em>is calculated adding the masses for all the atoms in the molecular formula:

Atom Number of atoms Atomic mass Total mass

g/mol g/mol

C 14 12.011 14 × 12.011 = 164.154

H 18 1.008 18 × 1.008 = 18.144

N 2 14.007 2 × 14.007 = 28.014

O 5 15.999 5 × 15.999 = 79.995

Total 294.307 g/mol

Answer: 294.307 g/mol
