If the values for both mass and volume double, the value of the density will be?

Stays the same.

Explanation:

Density = mass/volume

So if :

M/V = D

And if we were to double mass(M) and volume (V)

2M/2V = D

It will stay the same because the 2 and 2 would cancel out and we'd get the same density as the original value.

i'm guessing this is from edg enuity so the answers would be, from top to bottom,
