The new height of the water is 17.7 mL
The density of a substance is simply defined as mass per unit volume of the substance. Mathematically, it is expressed as:
Density = mass / volume
With the above formula, we can obtain the volume of the copper. This can be obtained as follow:
Mass of copper = 20 g
Density of copper = 8.96 g/mL
Volume of copper =?
Density = mass / volume
8.96 = 20 / volume
Cross multiply
8.96 × Volume = 20
Divide both side by 8.96
Volume = 20 / 8.96
Volume of copper = 2.2 mL
Finally, we shall determine the new height of the water. This can be obtained as follow:
Initial height of water = 15.5 mL
Volume of copper = 2.2 mL
New height of water =?
New height of water = (Initial height of water) + (Volume of copper)
New height of water = 15.5 + 2.2
New height of water = 17.7 mL
Therefore, the new height of the water is 17.7 mL
