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>
Use the formula A(t)=P(1+[r/n])^(n)(t) which for us looks like this:
A(t)= 3000(1+[.038/4])^(4)(9). Doing that math, you have 3000(1.405489). The product of that is $4216.47
