QUESTION 5
How many molecules are in 5.47E0 moles of carbon dioxide?

6.02 x 10²³molecules

Explanation:

From the problem statement, we have been given the number of moles of the carbon dioxide to be 5.47°;

  Any number raised to the power of 0 is 1,

So,

 The number of carbon dioxide is 1

From mole concept;

    1 mole of any substance contains 6.02 x 10²³molecules

The number of molecules in the carbon dioxide is 6.02 x 10²³molecules

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

the answer is c i took the test
