How many moles are in 8.8 x 1024 atoms of magnesium?

Chemistry
1 answer:
Veseljchak [2.6K]3 years ago
4 0

Answer:

15 mol Mg

Explanation:

Step 1: Find conversions

Avagadro's Number: 6.022 × 10²³

Step 2: Use Dimensional Analysis

8.8(10)^{24} \hspace{3} atoms \hspace{3} Mg(\frac{1 \hspace{3} mol \hspace{3} Mg}{6.022(10)^{23} \hspace{3} atoms \hspace{3} Mg} ) = 14.6179 mol Mg

Step 3: Simplify

We have 2 sig figs.

14.6179 mol Mg ≈ 15 mol Mg

In an electrochemical cell, electrons travel in which direction? * (a) from the anode to the cathode through the external circui
kompoz [17]

Answer:

(a) from the anode to the cathode through the external circuit

Explanation:

In an electrochemical cell, there are two half cells; the oxidation half cell and reduction half cell. Oxidation typically refers to loss of electrons and reduction refers to gain of electrons.

Electrons always flow from the anode to the cathode or from the oxidation half cell to the reduction half cell.

The electrical circuit in an electrochemical cell confirms the flow of electron. Usually a light bulb is attached. The correct option is;

(a) from the anode to the cathode through the external circuit

A mixture of three noble gases has a total pressure of 1.25 atm. The individual pressures exerted by neon and argon are 0.68
Novosadov [1.4K]

Answer:

0.22 atm

Explanation:

The total pressure is the sum of the partial pressures.

P = P₁ + P₂ + P₃

1.25 atm = 0.68 atm + 0.35 atm + P

P = 0.22 atm

Calculate the number of moles of C2H6 in 6.29×1023 molecules of C2H6.
Kipish [7]

1.05moles

Explanation:

Given parameters:

Number of molecules of C₂H₆ = 6.29 x 10²³molecules

Unknown:

Number of moles = ?

Solution:

The mole is the amount of substances that contains Avogadro's number of particles i.e 6.02 x 10²³

 To find the number of moles:

  number of moles = \frac{number of particles}{Avogadro's number}

  number of moles = \frac{6.29 x 10^{23} }{6.02 x 10^{23} }

  number of moles = 1.05moles
