The density of a 10 kg cube of silver is 10.5 g/cm³. What would the density of a 5 kg cube of silver be?

I thought the answer would be 5.25 g/cm^3 because m1/m2=p1/p2 so 10kg/5kg=10.5 g/cm^3/ x and you solve for x. But this is coming up as wrong and I don't know why, do i need to convert the kg to g???

Expert Solution

Density of a substance is total mass of that substance divided by total volume occupied by that substance.

If there is no change in temperature or pressure density of a substance remains same. Its SI unit kg/m³

Given density of a 10 kg cube of silver is 10.5 g/cm³

So this cube will occupy certain volume V.

------------

Now What would the density of a 5 kg cube of silver be?

Actually density does not change.

The 5 kg cube occupies less volume

Which is half of volume of 10 kg cube

ANSWER:

====================

No need to solve for x .that method is wrong.

You do have to convert either mass or density . I converted kg to gram.
