Answer:

4.61 x 10^23

Explanation: Convert 213g of PbCl2 to mol, which is 0.7658950184462004, multiply 0.765 with 6.022 x 10^23.

1 mole is equal to 6.023 × 10 ²³ molecules. 4.61 x 10^23 formula units is 213 g of PbCl2.

The term mole is defined as the amount of substance of a system which contains as many elementary entities.

One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.

The mole concept can be used to convert between mass and number of particles.

Convert 213g of PbCl2 to mol,

1 mole is equal to the 6.023 × 10 ²³ molecules

1 mole of PbCl2 is equal to the  6.023 × 10 ²³ molecules

which is 0.7658950184462004, multiply 0.765 with 6.022 x 10^23.

= 0.765 × 6.022 x 10^23

= 4.61 x 10^23

Thus, 4.61 x 10^23 formula units is 213 g of PbCl2.

i do not know this one ooooo

Answer:

They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.

Explanation:

That pull is gravity at work. Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but the Gravity or gravitational forces are forces of attraction. We're not talking about finding someone really cute and adorable. It's like the Earth pulling on you and keeping you on the ground. That pull is gravity at work.

Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but that force isn't very strong, since people aren't very massive. When you look at really large masses, like the Earth and Moon, the gravitational pull becomes very impressive. The gravitational force between the Earth and the molecules of gas in the atmosphere is strong enough to hold the atmosphere close to our surface. Smaller planets, that have less mass, may not be able to hold an atmosphere.at force isn't very strong, since people aren't very massive.

Obviously, gravity is very important on Earth. The Sun's gravitational pull keeps our planet orbiting the Sun. The motion of the Moon is affected by the gravity of the Sun AND the Earth. The Moon's gravity pulls on the Earth and makes the tides rise and fall every day. As the Moon passes over the ocean, there is a swell in the sea level. As the Earth rotates, the Moon passes over new parts of the Earth, causing the swell to move also. The tides are independent of the phase of the moon. The moon has the same amount of pull whether there is a full or new moon. It would still be in the same basic place.

Answer:

0.94 mol NaCl

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

55g NaCl

Step 2: Identify Conversions

Molar Mass of Na - 22.99 g/mol

Molar mass of Cl - 35.45 g/mol

Molar Mass of NaCl - 22.99 + 35.45 = 58.44 g/mol

Step 3: Covert

[tex]55 \ g \ NaCl(\frac{1 \ mol \ NaCl}{58.44 \ g \ NaCl} )[/tex] = 0.941136 mol NaCl

Step 4: Check

We are given 2 sig figs. Follow sig fig rules and round.

0.941136 mol NaCl ≈ 0.94 mol NaCl

In 55 grams of sodium chloride (NaCl), 0.94 moles of NaCl is present.

Number of moles of any substance is defined as:

n = W / M

Where, W = given mass or weight

M = molar mass

In the question given weight of NaCl is 55 g.

And molar mass of NaCl is 58.44 g/mol

Now we put all these values in the above equation, we will get:

n = 55 / 58.44 = 0.94 mol

Hence, 0.94 mole of NaCl is present in 55g of NaCl.
