Sofia is trying to find the density of a 25.0 g irregularly shaped solid. She filled a graduated cylinder with 25.0 mL of water.

After adding the solid the water rises to 56.5 mL. What is the density of the solid? Does this solid float or sink in water

The volume of the solid is
56.5 ml - 25 ml = 31.5 ml
The mass of the solid = 25g
So the density is Mass/ Volume
25/ 31.5 = 0.79 g/ml

Since the solid has a lower density (0.79 g/ml) than the density of water (1g/ml) it will float on water

Answer:  Density:  0.794 g/ml.  It would float.

Explanation:  The mass of 25.0 grams displaces (56.5 - 25.0) = 31.5 ml of water, it's volume (when submerged).  Density is mass per unit volume:

25.0 grams/31.5 ml = 0.794 g/ml

Water's density is 1 g/ml, so this obect would float.  (Don't ask me why it displaced 31.5 ml.  It won't unless it is pushed down, then the volume of the finger needs to be determined and subtracted from the calculated volume.

Why is U-235 the most common nuclear fuel instead of the more abundant U-238? State a clear topic sentence and support it with e
GREYUIT [131]
<h3><u>Answer and explanation</u>;</h3>
  • <em><u>The isotope U-235 is an important common nuclear fuel because under certain conditions it can readily be split, yielding a lot of energy. It is therefore said to be 'fissile' and use the expression 'nuclear fission'.</u></em>
  • <em><u>Uranium 238 on the other hand is not fissionable by thermal neutrons, but it can undergo fission from fast or high energy neutrons. Hence it is not fissile, but it is fissionable.</u></em>
  • In a nuclear power station fissioning of uranium atoms replaces the burning of coal or gas.  Heat created by splitting the U-235 atoms is then used to make steam which spins a turbine to drive a generator, producing electricity.
