How many moles are in 4.67 x 10^26 atoms of Iron?
TiliK225 [7]

Answer:

<h2>775.75 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{4.67 \times  {10}^{26} }{6.02 \times  {10}^{23} }   \\  = 775.747508...

We have the final answer as

<h3>775.75 moles</h3>

Hope this helps you

What is the approximate pH of a .06 M solution of CH3COOH given that Ka= 1.78*10-5
Step2247 [10]
CH₃COOH ⇔ CH₃COO⁻ + H⁺

[CH₃COO⁻] = [H⁺] = x

K=\frac{|CH_{3}COO^{-}|*|H^{+}|}{|CH_{3}COOH|}=\frac{x^{2}}{|CH_{3}COOH|}\\\\&#10;1,78*10^{-5}=\frac{x^{2}}{0,06} \ \ |*0,06\\\\&#10;0,1068*10^{-5}=x^{2}\\\\&#10;x_{1}\approx0,001 \ \land \ \ x_{2}=\approx-0,001\\\\&#10;pH=-log|H^{+}|=-log0,001=3
