Help me find how many moles

H 13.8mol CO2

Explanation:

we know that per 1 mol there is 6.022x10^23 molecules

so divide 8.23x10^22/ AVG # ( # above) we get 13.8mol of CO2 not to be confused with A

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
