Methane, CH4 burns in oxygen gas to form carbon dioxide and water. How many moles of carbon dioxide will be formed from 8.0g of methane?

CH4 + 2O2 ==> CO2 + 2H2O

Convert 8.0 g CH4 to moles. moles = grams/molar mass.
8.0/16 = 0.5 mole CH4.
Now look at the equation. The equation tells us that 1 mole CO2 is formed for 1 mole CH4; therefore, 0.5 mole CO2 will be formed by 0.5 mole CH4.

answer

Well, let's see! To figure out how many moles of carbon dioxide will be formed, we'll first need to determine the molar mass of methane (CH4) and carbon dioxide (CO2).

The molar mass of carbon is 12.01 g/mol, and the molar mass of oxygen is 16.00 g/mol. Since methane has one carbon atom and four hydrogen atoms, we can calculate its molar mass:

1 carbon atom (12.01 g/mol) + 4 hydrogen atoms (1.01 g/mol each) = 16.05 g/mol

Next, carbon dioxide has one carbon atom and two oxygen atoms, so we can calculate its molar mass:

1 carbon atom (12.01 g/mol) + 2 oxygen atoms (16.00 g/mol each) = 44.01 g/mol

Now, we can use the molar mass of methane to convert grams to moles:

8.0 g methane × (1 mol methane / 16.05 g methane) = 0.498 mol methane

Finally, we can use the balanced chemical equation to determine the ratio of moles of methane to moles of carbon dioxide. According to the equation:

1 mol methane produces 1 mol carbon dioxide

Since the ratio is 1:1, we can say that 0.498 moles of carbon dioxide will be formed from 8.0 grams of methane.

But hey, if you need any more help, I'm here to assist you!

To calculate the number of moles of carbon dioxide formed from a given mass of methane, we need to use the molar masses of methane (CH4) and carbon dioxide (CO2).

Step 1: Find the molar mass of methane (CH4).
To calculate the molar mass of methane, we sum up the atomic masses of each element present in methane.
The atomic mass of carbon (C) is 12.01 g/mol, and the atomic mass of hydrogen (H) is 1.01 g/mol.
Molar mass of CH4 = (1 * molar mass of C) + (4 * molar mass of H)
Molar mass of CH4 = (1 * 12.01) + (4 * 1.01)
Molar mass of CH4 = 16.05 g/mol

Step 2: Find the molar mass of carbon dioxide (CO2).
Similarly, for carbon dioxide, the atomic mass of carbon (C) is 12.01 g/mol, and the atomic mass of oxygen (O) is 16.00 g/mol.
Molar mass of CO2 = (1 * molar mass of C) + (2 * molar mass of O)
Molar mass of CO2 = (1 * 12.01) + (2 * 16.00)
Molar mass of CO2 = 44.01 g/mol

Step 3: Calculate the number of moles of carbon dioxide (CO2).
We can use the following formula to calculate the number of moles:
Number of moles = Mass / Molar mass

Given mass of methane (CH4) = 8.0 grams

Number of moles of carbon dioxide (CO2) = 8.0 grams / Molar mass of CH4 * (1 mole CO2 / 1 mole CH4) * Molar mass of CO2
Number of moles of carbon dioxide (CO2) = 8.0 / 16.05 * (1/1) * 44.01
Number of moles of carbon dioxide (CO2) = 2.75 moles

Therefore, 8.0 grams of methane will form 2.75 moles of carbon dioxide.

Hey so not too hard.

1. write the balanced equation: CH4+2O2->CO2+2H2O
2. convert 8.g of CH4 to moles (n=m/M): 8.0/16=0.5 mole CH4
3. refer to the above equation- it states that 1 mole CO2 is formed for 1 mole CH4 (giving the ratio 1:1) and therefore, means 0.5 mole CO2 will be formed by 0.5 mole CH4
