Rosemary Jenkins · Answer 1

Density equals mas divided by volume. You know the density and mass so use it to solve for the volume.

d = m/v

d = 19.3 g/mL

m = 50g

v=?

Plug it in. 19.3 = 50/v

To solve for v you do the opposite of 50 divided by v which is 50 time v.

That cancels v from the right side of the equation. Do the same on the other side (times v)

19.3 * v=50

Now just divide both sides by 19.3 to get v alone.
