How many moles are in 3.86 x 1023 molecules of Carbon Dioxide (CO2)?

Chemistry
1 answer:
Yuri [45]3 years ago
3 0

Answer:

<h2>0.64 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{3.86 \times {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{3.86}{6.02}  \\  = 0.641196...

We have the final answer as

<h3>0.64 moles</h3>

Hope this helps you

What is the change in internal energy ( ΔU ) of the system if q = –8 kJ and w = –1 kJ for a certain process?
Radda [10]

Answer:

Change in internal energy (ΔU) = -9 KJ

Explanation:

Given:

q = –8 kJ [Heat removed]

w = –1 kJ [Work done]

Find:

Change in internal energy (ΔU)

Computation:

Change in internal energy (ΔU) = q + w

Change in internal energy (ΔU) = -8 KJ + (-1 KJ)

Change in internal energy (ΔU) = -8 KJ - 1 KJ

Change in internal energy (ΔU) = -9 KJ
