So the way to determine is to find the density of your unknown metal. To do that, you know density is g/mL or g/cm3. So, you do 979/58. It is approximately 16.88 g/mL. So, the density is more than pure gold. (A)
I’m not 100% sure that mL = cm3 for this case so make sure you check that but that’s what I think the answer is!
