Given 1 cc of Zinc and 1 cc of Cr What is the mass difference?
mass = volume x density.
mass Zn = 1 x density Zn (you will need to look that up).
mass Cr = 1 x density Cr. Look up density Cr also.
Then subtract to find mass difference.
mass Zn = 1 x density Zn (you will need to look that up).
mass Cr = 1 x density Cr. Look up density Cr also.
Then subtract to find mass difference.
