What is the density, in g/mL, of a cube of lead (Pb) that weighs 0.371 kg and has a volume of 2.00 in.3

Chemistry

Answer:

11.32 g/mL

Explanation:

Given that:-

Mass = 0.371 kg = 371 g ( 1 kg = 1000 g)

Volume = 2.00 in³

The conversion of in³ to mL is as shown below:-

1 in³ = 16.3871 mL

So, Volume = 2.00\times 16.3871\ mL = 32.7741 mL

The expression for the calculation of density is shown below as:-

\rho=\frac{m}{V}

Applying the values as:-

\rho=\frac{371\ g}{32.7741\ mL}=11.32\ g/mL

Which is true of a solute dissolved in a solvent? the solute raises the boiling point of the solvent. the solvent decreases the
Lina20 [59]
When a solute is dissolved in a solvent the solute raises the boiling point of the solvent. The boiling point of a liquid (a solvent) will be higher when another compound (solute) is added, such that a solution has a higher boiling point than a pure solvent. This takes place when a non-volatile solute, such as a salt, is added to a pure solvent such as water.

How many atoms are in 5 mole of water?<br> Steps
Vladimir79 [104]

Answer: 3.01 x 10^24 atoms

Explanation:

Based on Avogadro's law:

1 mole of any substance has 6.02 x 10^23 atoms

So, 1 mole of water = 6.02 x 10^23 atoms

5 moles of water = Z atoms

To get the value of Z, cross multiply

Z x 1 mole = (6.02 x 10^23 atoms x 5 moles)

Z•mole = 30.1 x 10^23 atoms•mole

Divide both sides by 1 mole

Z•mole/1 mole = 30.1 x 10^23 atoms•mole/ 1 mole

Z = 30.1 x 10^23 atoms

[Place the value of Z in standard form]

Z = 3.01 x 10^24 atoms

Thus, there are 3.01 x 10^24 atoms in 5 mole of water

Why do covalent bonds form between elements with similar electronegativity?
sesenic [268]

A COVALENT BOND, FORMS BETWEEN ELEMENTS WITH SIMILAR  ELECTRONEGATIVITY AS SHARING OF ELECTRON PAIRS BETWEEN ATOMS IS EASIER AS THEY ARE IDENTICAL.

Explanation:

Bonding atoms with similar electronegativity values form covalent bonds.

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.

Covalent bonds form between two nonmetal atoms with identical or relatively close electronegativity values

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons, also it is the strength an atom has to attract a bonding pair of electrons to itself.

Pure covalent bonds result when two atoms of the same electronegativity bond. This occurs only when two atoms of the same element bond with each other.

Please Explain. Why does salt water boil at a lower temperature than tap water?
nexus9112 [7]
We observe that heat capacity of salted water we will find that it is less than pure water. We now that it takes less energy to increase the temperature of the salt water 1°C than pure water. Which means that the salted water heats up faster and eventually reaches to its boiling point first.
