Answer:

\huge 3.322 \times  {10}^{ - 5}  \:  \: moles  \\

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{2.00 \times  {10}^{19} }{6.02 \times  {10}^{23} }  \\  \\  = 3.322 \times  {10}^{ - 5}  \:  \: moles

Hope this helps you

Calculate the eccentricity of an ellipse. The distance between the foci is 5.2 and the length of the major axis is 20.6.Round of
Dominik [7]

Answer:

The eccentricity of the ellipse is 0.252.

Explanation:

The eccentricity of an ellipse (c), dimensionless, can be determined by means of the following expression:

e = \frac{\bar c}{\bar a} (1)

Where:

\bar c - Distance between the foci, dimensionless.

\bar a - Length of the major axis, dimensionless.

If we know that \bar c = 5.2 and \bar a = 20.6, then the eccentricity of the ellipse is:

e = \frac{5.2}{20.6}

e = 0.252

The eccentricity of the ellipse is 0.252.
