How many molecules are in 2.10 mol CO2?
A. 2.53 x 10^24 molecules
B. 3.79 x 10^24 molecules
C. 3.49 x 10^24 molecules
D. 1.26 x 10^24 molecules***
I think it is D, but can someone check my work?
Amount of mols x Avogadro's number (2.10 x 6.02 x 10^23)
1.26 x 10^24
(P.S This is all scientific notation)
Thank you!
