An irregular shaped piece of metal wha a mass of 0.251 lb was placed into a graduated cylinder containing 50.00 mL of water; this raised the water to 67.50 mL. What is the density, in g/cm3, of the metal?

Explanation:

Hello!

In this case, since the density is defined as the degree of compactness of a substance, and is defined as the mass over the volume:

Given the displaced volume, we can compute the volume of the piece of metal via the following subtraction:

Since the piece of metal displaces the water to the final volume. Moreover, given the mass in lb, we compute it grams as follows:

Thus, the density turns out:

Best regards.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
