Homework Help: Carbon cube.

  1. Oct 27, 2012 #1
    Hello,

    If the distance between carbon atoms is given as 3A, will a 12 gr carbon cube have a volume of (6.022E23)*(27E-24)cm^3?

    wouldn't you need to take the cube root of avogadros number to determine how many carbon atoms are on an edge?

    Doesn't seem quite right. Show how you get the 6.022E23.

    Avogadro's number. Wouldn't that be the right way to calculate the volume?

    OK, yes. I came at it a slightly different way and got a different answer, but I must have made a mistake.
