How many moles of CO2 are there in 8.91 x 1023 molecules of CO2?<br> (1 mole= 6.02 x 1023)
Karo-lina-s [1.5K]

Answer:

<h2>1.48 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{8.91 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{8.91}{6.02}  \\  = 1.480066...

We have the final answer as

<h3>1.48 moles</h3>

Hope this helps you
