Answer:

The density of the metal is 7 \frac{g}{mL}

Explanation:

Density is a quantity that allows you to measure the amount of mass in a given volume of a substance. The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

Density, according to the International System of Units, is usually expressed in kilogram per cubic meter (\frac{kg}{m^{3}  }) or gram per cubic centimeter (\frac{g}{cm^{3} }). Although it can also be expressed in any other unit of mass by volume.

In this case you know:

  • mass= 147 g
  • volume= 21 mL

Then:

density=\frac{147 g}{21 mL}

density= 7 \frac{g}{mL}

<u><em>The density of the metal is 7 </em></u>\frac{g}{mL}<u><em></em></u>

Agata [3.3K]
Yes, that is completion reaction.
<span>This type of reactions do not set up an equilibrium and goes until one of the reactants runs out.
</span>Three major types of completion reactions are:
1. <span>Formation of a slightly ionized product (for example mixture of sodium bromide and potassium chloride).
</span>2. <span>Formation of a gas (for example hydrogen gas from metal and acid).
3.</span> Formation of a precipitate (feor example silver chloride).<span>

Why do chemists routinely test existing chemicals
PIT_PIT [208]

Answer:

The chemists such as analytical chemists determine the structure, composition, and nature of substances by examining and identifying their various elements or compounds. These chemists are crucial to the pharmaceutical industry because pharmaceutical companies need to know the identity of compounds that they hope to turn into drugs.
