Ok, I just want to make sure I am doing this right. It says mass= 3800grams. Silvers density is 10 grams/cm^3. How much will volume of water with silver displace in cm^3?

So would it be 3800g/10g= 380 grams?
or is that wrong?

No but mostly because volume is not measured in grams but in cc or cm^3.

volume = mass/density = 3800 g/10 g/cc = 380 cc
