How many molecules are 4.3 x 10^27 molecules of N2O5<br>​
horrorfan [7]

Answer:

<h2>7142.86 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{4.3 \times  {10}^{27} }{6.02 \times  {10}^{23} }  \\  = 7142.857...

We have the final answer as

<h3>7142.86 moles</h3>

Hope this helps you

What happens to the ions when the drain is turned off? please help :] ❤️
kkurt [141]

Answer:

In a long channel MOSFET, the width of the pinch-off region is assumed small relative to the length of the channel. Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the drain current saturates.
