How many moles are in 1.9 x 1046 atoms of chromium?
faust18 [17]

Answer:

<h2>3.156 × 10²² atoms</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{1.9 \times  {10}^{46} }{6.02 \times  {10}^{23} }  \\  = 3.156 \times  {10}^{22}

We have the final answer as

<h3>3.156 × 10²² atoms</h3>

Hope this helps you
