How many moles are there in 8.50 X 1024 molecules of sodium sulfate, Na2SO3?
il63 [147K]

Answer:

<h2>14.12 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{8.50 \times  {10}^{24} }{6.02 \times  {10}^{23} }  \\  = 14.119601...

We have the final answer as

<h3>14.12 moles</h3>

Hope this helps you

Group 1A element sodium combines with Group 7A element chlorine to form sodium chloride or table salt. Based on this information
Ymorist [56]
The answer is Na < Cl

Chlorine is more electronegative than sodium because this follows the trend of the periodic table. The trend states that an element's electronegativity increases from left to right of a period and bottom to up of a group. Since sodium and chlorine are from the same period, and chlorine is at the right of sodium, chlorine is more electronegative.
