3. How many moles of glucose does 1.2 x 1024 molecules represent?

Answers

Answer 1
The answer is two miles


1 mole of any substance has 6.02 x 1023 molecules. For getting thenumber of moles we can divide 1.2 x 1024/6.02 x 1023 and we receive 2 moles.
Answer 2

It measure the number of elementary entities of a given substance that are present in a given sample. 1.99 moles of glucose are present in 1.2 x 10²⁴  molecules.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance. The stoichiometry represents the number of moles. Mole is directly proportional to the number of given molecules.

Given number of atoms= 3.01x10²³atoms

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

mole of glucose =given number of molecules of glucose ÷ 6.022×10²³(Avogadro number)

Substituting the values, we get

mole of glucose= 1.2 x 10²⁴÷6.02 x 10²³

mole of glucose= 1.99 moles

Therefore, 1.99 moles of glucose are present in 1.2 x 10²⁴  molecules.

What happens to the average kinetic energy at a constant temperature? *

1.it increases
2.it decreases
3.it stays the same
4.it disappears

Answers

The answer is A, it increases.


As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.

Answers

Answer:

0,1276 M

Explanation:

Molair mass of NaOCl = 74,44 g/mol

You have 9,5 g/L.

You need to calculate with the molair mass, how many moles 9,5 g are:

9,5 g / 74,44 g/mol = 0,1276 mol

0,1276 mol / 1 L = 0,1276 M

The molarity of a bleach solution containing 9.5 g of NaOCL per liter of bleach is mathematically given as

M= 0.1276 M

What is the molarity of a bleach solution containing 9.5 g of NaOCL per liter of bleach?

Generally, the equation for the  Molar mass  is mathematically given as

M=m/(g/mol)

Therefore

M=9,5 g / 74,44 g/mol

M= 0,1276 mol

Hence

M= 0.1276 M

In conclusion, the molarity

M= 0.1276 M

How many atoms are found in a 15.5 g sample of bismuth?

Answers

Answer:

4.47 x 10²² atoms

Explanation:

Given parameters:

Mass of Bismuth  = 15.5g

Unknown:

Number of atoms  = ?

Solution:

To find the number atoms, first solve for the number of moles in this element first.

  Number of moles  = [tex]\frac{mass}{molar mass}[/tex]    

  Number of moles  = [tex]\frac{15.5}{209}[/tex]    = 0.074mole

So:

        1 mole of a substance contains 6.02 x 10²³ atoms

     0.074 mole of Bismuth will contain 0.074 x 6.02 x 10²³ atoms

                                                          = 4.47 x 10²² atoms

Answer  C) 6 × 1023 atom

The number of silver atoms present in one mole of silver is 6.0 × 10²³ atoms. The correct option is C) 6 × 1023 atoms

Stoichiometry

From the question, we are to determine the number of silver atoms present in one mole of silver.

From the formula,

Number of atoms = Number of moles × Avogadro's constant

Number of atoms = 1 × 6.022 × 10²³

Number of atoms = 6.022 × 10²³

Number of atoms ≅ 6.0 × 10²³ atoms

Hence, the number of silver atoms present in one mole of silver is 6.0 × 10²³ atoms. The correct option is C) 6 × 1023 atoms
