Question

Calculate the number the number of moles in 3.011 X 1022 molecules of carbon dioxide. ​

Answer 1

Answer:

3.011×1022 = 3,077.242

Explanation:

3,077.242 molecules of carbon dioxide

Answer 2

Answer:

Solution:-

There are so many formula to find out no of moles.

If mass is given,

mole = given mass/molar/atomic mass

If volume is given at STP/NTP,

mole = given volume (in L)/22.4 L

If the no of atoms/molecules is given,

mole = number of atoms/molecules/

Avogadro's number

Now see your questions once again, here no of molecules of carbon dioxide is :-

I.e., mole = no of molecules/Avogadro's number

Here no of molecules = 3.011 x 10²²

Avogadro's number = 6.022 x 10²³

So, mole = 3.011 x 10²²/6.022 x 10²³

=> 1/20

=> 0.5 (ans)
