<span>molecular weight of C4H10 is = 58.1 grams

moles of butane  = </span>\frac{1.5}{58.1}  = 0.0258

Multiply the number of moles by Avogadro's number. This will let you obtain the number of butane molecules: 

<span>0.0258 x 6.023 x 10^{23} molecules of butane = 1.5538 * 10^22 molecules
of butane 
</span>
<span>Now multiply this number by four (due to four carbon atoms per butane molecule) to obtain the answer: 
</span>
so, no. of carbon atoms = 4 x 1.5538 x 10^22  =  6.21 x 10^22 atoms

6,237.10²² atoms are in 1.50 g of butane

<h3><em>Further explanation</em></h3>

Stokiometry in Chemistry learn about chemicals mainly emphasizes quantitative, such as the calculation of volume, mass, number, which is related to numbers, molecules, elements, etc.

In stoichiometry therein includes

  • 1. the relative atomic mass (Ar) is a measurement of the mass of an atom relative to the mass of 1 carbon-12 atom
  • 2. The relative molecular mass (M) is the sum of the mass of all the atomic masses that make up the molecule or is the sum of the relative atomic masses that make up the molecule

M X = (average mass of 1 molecule AxBy) / 1/12 mass 1 atom C-12

M AxBy = (x.Ar A + y. Ar B)

  • 3. Mole is a unit of the number of particles where 1 mole is the number of particles contained in a substance (atom, molecule)which is equal to atoms in 12 gr C-12

1 mol = 6.0210²³ particles

While the number of moles can also be obtained by dividing the mass (in grams) by the relative mass of the element (Ar) or the relative molecular mass (M)

mole = gram / (Ar / M)

For example

1 mole of H element contains 6.02 × 10²³ H atoms

1 mole of water contains 6.02 × 10²³ water molecules.

1 mole of KCl ion  contains 6.02 × 10²³ K⁺ ions and 6.02 × 10²³ Cl⁻ ions.

We know Butane molar mass = 58 grams / mol and mass known to be 1.5 grams so the number of moles:

mole = gram / M

mole = 1.5 / 58

mole = 0.0259

So the number of moles of C atoms in Butane is:

= 4 (valence C) x number of moles of Butane

= 4. 0.0259

= 0.1036 moles

So the number of atoms of element C is

= 0.1036 x 6.02 × 10²³

= 6,237.10 ^ 22 atoms

How is the periodic table arranged
Mashcka [7]
The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

Drag the tiles to the correct boxes to complete the pairs.
iragen [17]

Answer:

Solid:- Particles vibrate in a rigid structure and do not move relative to their neighbors.

Liquid:- It takes the shape of its container but keeps a constant volume.

Gas:- Particles move rapidly and independently of each other.

Plasma:- It is the most common state of matter in the universe.

Explanation:

Solids are one of the three states of matter and, unlike liquids or gases, they have a definite shape that is not easy to change. Different solids have particular properties such as stretch, STRENGTH, or hardness that make them useful for different jobs.

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure

Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed. The particles exert more force on the interior volume of the container.

A plasma is a gas that has been energized to the point that some of the electrons break free from, but travel with, their nucleus.
