How many molecules of carbon dioxide are present in 4.81042 mol of that substance?

1 mol is equal to 6.02×10∧23 molecules.

first put in the calculator 4.81042 × 6.02 then hit EXP or 2nd then EE. (Depends on the type of calculator). then put in 23 and press equal.

The calculator will says 2.89587284×10∧24.

So the answer will be 2.90×10∧24.

I mot sure if the 2.90 is correct but it is close to the answer. it really depends how you want to round it. As long as the decimals are close the answer doesn't matter. Hope this helps. Please mark as Brainliest.
