How many moles of CO2 can be formed from 10 g of CH4?

Chemistry

Furkat [3]1 year ago
6 0

Answer:

0.625 moles of CO2

Explanation:

Remark

The equation used (I take it) is a hydrocarbon burning. If it is not, leave a note on the question. The method I will use is

  • Find the moles CH4
  • Use the equation to adjust the number of moles of the product. It the balance numbers are the same, move on.

Equation

CH4 + 2O2 ====> CO2 + 2H2O

Givens

10 grams CH4

Solution

Number of moles of CH4

mol CH4 = given mass / molar mass.

given mass = 10 grams

molar mass CH4

  • C =               12
  • H = 4 * 1   <u>     4</u>
  • molar mass  16

Moles of  CH4

mol = given mass / molar mass

mol = 10 grams / 16 grams

mol = 0.625

Answer

Since the number of moles of CO2 and CH4 are the <u><em>same </em></u>in the  balanced equation. the answer is 0.625 mols of both.

Calculate the number of moles in the following: 2.8 X 10^24 atoms of Cl2
vova2212 [387]

Answer:

<h3>The answer is 4.65 moles</h3>

Explanation:

To find the number of moles given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

N = 2.8 × 10²⁴ atoms of Cl2

So we have

n =  \frac{2.8 \times  {10}^{24} }{6.02 \times  {10}^{23}  }  \\  = 4.65116279069...

We have the final answer as

<h3>4.65 moles</h3>

Hope this helps you
