What is the formula mass of NaCl?

Answers

Answer:

The molar mass of sodium is 22.990 g/mol.

The molar mass of chlorine is 35.45 g/mol.

To calculate the molar mass of NaCl, we need to multiply the subscript of each element times its molar mass, then add them together. In this case since there is no subscript, it is understood to be

( 1 × 22.990 g/mol ) + ( 1×35.45 g/mol ) = ?

22.990 g/mol + 35.45 g/mol = ?

58.44 g/mol = ?

Calculate the number of sucrose molecules in a 75.0 gram sample.

Answers

Answer:

1.32*10^23 molecules

Explanation:

sucrose formula: C12H22O11

molar mass: 12(12.01)+22(1.01)+11(16.00)=342.34g/mol

75.0 g C12H22O11 * (1 mol C12H22O11)/(342.34g C12H22O11)=0.219 mol C12H22O11

0.219 mol * (6.022*10^23)/mol = 1.32*10^23 molecules (three sig. figures)

Which pair best represents a metallic bond?
A. carbon and oxygen two
B. hydrogen atoms two
C. gold atoms
D. sodium and chlorine

Answers

Answer:

C. gold atoms

Explanation:

Metallic bonds are found between atoms of metals. Since gold is the only metal given here, it is the solution to the problem.

Metallic bonds join atoms of metals and alloys together.

The formation of this type of bond is favored by large atomic radius, low ionization energy and a large number of electrons in the valence shell.

The metallic bond is actually an attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by all atoms losing their outermost shell electrons.

A compound is determined to have the empirical formula C2OH4. If the molar mass of the compound is 132 g/mol, determine the molecular formula of the compound.

Answers

Answer: The molecular formula will be [tex]C_6O_3H_{12}[/tex]

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.  

Empirical weight of [tex]C_2OH_{4}[/tex] is [tex]12\times 2+16\times 1+1\times 4=44g[/tex]

Molecular mass of compound is = 132 g

Now we have to calculate the molecular formula.

[tex]n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=\frac{132}{44}=3[/tex]

The molecular formula will be=[tex]3\times C_2OH_4=C_6O_3H_{12}[/tex]

Compared to atoms of metals, atoms of nonmetals generally
A)have higher electronegativities
B)have lower first ionization energies
C)conduct electricity more readily
D)lose electrons more readily

Answers

The answer for the question is C

Compared to atoms of metals, atoms of nonmetals generally conduct electricity more readily. Therefore, option C is correct.

What are metal atoms ?

The term metal atom is defined as an atom of an element that exhibits typical metallic properties, being typically shiny, with high electrical and thermal conductivity.

Metallic bonds form when the charge is spread over a greater distance than the size of individual atoms in solids. Most left elements in the periodic table form metallic bonds, such as zinc and copper.

Metals are defined as elements to the left of the line. Elements just to the right of the line have both metal and nonmetal properties and are referred to as metalloids. Nonmetals are elements at the far right of the periodic table.

Thus, option C is correct.
