Explanation:
Use the formula D=m/v
Density equals mass divided by volume. Plug in your numbers and use algebra to solve. For example the first one the density is 12. So plug that into the equation you get 12=m/v, we also know the mass, plug that into the equation and we get 12=24/v. So now we solve for v. Multiply both sides by v and we get 12v=24. Divide both sides by 12 and we get v=2. So your volume would be mL.
