Answer:

E = h v = 6.626 x 10^{-34} x 97.20 x 10^{-9} = 6.44 x 10^{-41} J = 4.01 x 10^{-22} eV

n = Energy Level = -E^{0} / E = -13.6 / 4.01 x 10^{-22} = 3.39 x 10^{22} = 1.84 x 10^{11} energy level...

How many moles are in 5.6x1025 molecules of calcium oxide?
Vlad1618 [11]

Answer:

<h2>93.02 moles</h2>

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{5.6 \times  {10}^{25} }{6.02  \times  {10}^{23} }  \\  = 93.023...

We have the final answer as

<h3>93.02 moles</h3>

Hope this helps you
