Answer:
The mass of 3.13*10²³ molecules of carbon dioxide is 22.88 g.
Step-by-step explanation:
Avogadro's Number or Avogadro's Constant is the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole and it applies to any substance.
Then you can apply the following rule of three: if 6.023*10²³ molecules are present in 1 mole, 3.13*10²³ molecules are present in how many moles?
moles= 0.52
Since the molar mass of carbon dioxide is 44 g / mole, then the following rule of three can be applied: if there are 44 g in 1 mole, how much mass is there in 0.52 moles?
mass= 22.88 g
<u><em>The mass of 3.13*10²³ molecules of carbon dioxide is 22.88 g.</em></u>
Answer:
5.13m^2
Explanation:
A = 1/2bh
A = 1/2(3.8)(2.7)
A = 5.13m^2
In geometry, the length of JK in terms of a, b, and x will be D. abx
<h3>How to illustrate the information?</h3>
It should be noted that from the information given, it was stated that in circle M, EMF measures the radians allocated, the length of radius FM is and the length of EF is x.
In the other circle, JNK also measures the radians allocated and the length of radius KN is b.
Therefore, the length of JK in terms of a, b, and x will be:
= a × b × x
= abx
