Question

calculate the mass (in grams) of 2.07X10^24 carbon atoms. use 12.01 g/mole for the atomic mass of carbon

Answer 1

Recall the constant: Avogradro's number

By dividing your molar mass [g / mole] by A's number [atom / mole], you will find the mass for an atom [g / atom]. Then, you simply need to multiply that value by the number of carbon atoms to find [g / atom] * [atom] = [g] the mass you are looking for.

Answer 2

I got 41.28312853....would this be correct? I am taking an online chemistry class and am getting no assistance from my professor. So I greatly appreciate all of your help on this.
