Calculate the mass of a liquid with density of 3.20 g/mL and volume of 15.0 mL.

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

Density = 3.20 g/mL

volume = 15.0 mL

Substitute the values into the above formula and solve for the mass

That's

mass = 3.20 × 15

We have the final answer as

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.
