How many moles are in 8.5 x 1025 molecules of co2? 5.1 1049 mol 7.1 x 10–3 mol 1.4 x 102 mol 8.5 x 1025 mol

Hey there!

1 mole of CO2 6.02*10²³ molecules

( ?? moles of CO2 ) 8.5 * 10²⁵ molecules

moles of CO2 =  ( 8.5*10²⁵ ) * 1 / ( 6.02*10²³ )

moles of CO2 =  8.5*10²⁵ / 6.02*10²³

moles of CO2 = 1.4 * 10² moles

Answer C

Hope that helps!

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
