<h2>Answer: 8.93 g/cm³</h2>

<h3>Explanation:</h3>

Density = mass ÷ volume

= 217.0 g ÷ 24.3 cm³

= 8.93 g/cm³

<h3>∴ the unknown sample of mass 217.0 grams and volume of 24.3 cm³ has a density of 8.93 g/cm³. </h3>

19. What is sthe mass of 6.02 x 1024 atoms

alekssr [168]

The mass of magnesium in $6.02 \times 10^{24}$ atoms is 240 g.

Answer: Option A

<u>Explanation:</u>

First, we have to convert the atoms to moles of magnesium.

We know that $6.02 \times 10^{24}$ atoms are present in 1 mole of magnesium. So,

$\text { 1 atom }=\frac{1}{6.02 \times 10^{24}} \text { moles }$

$6.02 \times 10^{24} \text { atoms }=\frac{6.02 \times 10^{24}}{6.02 \times 10^{23}} \text { moles }=10 \text { moles }$

Thus,

$Mass of M g= molar mass of M g \times No. of moles of M g$

$\text { Mass of } M g=24 \times 10=240 g$

Thus, 240 g of Magnesium is present in $6.02 \times 10^{24}$ atoms.

What type of chemical bond involves the sharing of a pair of electrons by two atoms in a molecule.

Over [174]

Answer:

Covalent bond.

Explanation:

There are two kinds of chemical bonds: covalent bonds and ionic bonds.

A covalent bond is formed when two atoms share a pair of electrons (two electrons for each bond.)
Ions are formed when one atom transfers an electron to another. Ionic bonds refer to the attraction between ions of opposite electric charges.

In this example, since the atoms are sharing atoms, the chemical bond between them would be a covalent bond.
