Convert 4.3 moles CO2 to molecules
Understand the Problem
The question is asking to convert a quantity of moles of CO2 into the number of molecules. This requires knowing that 1 mole of any substance contains Avogadro's number of molecules, which is approximately 6.022 x 10^23.
Answer
$1.2044 \times 10^{24}$ molecules
Answer for screen readers
The total number of molecules in 2 moles of CO2 is approximately $1.2044 \times 10^{24}$ molecules.
Steps to Solve
- Identify the number of moles
Let’s say we have $n$ moles of CO2. For example, if the problem states we have 2 moles of CO2, we will use $n = 2$.
- Understanding Avogadro's Number
Recall that 1 mole of any substance contains approximately $6.022 \times 10^{23}$ molecules. This is a constant value known as Avogadro's number.
- Calculate the number of molecules
To get the total number of molecules, we multiply the number of moles ($n$) by Avogadro's number ($N_A$). The formula will be:
$$ \text{Number of molecules} = n \times N_A $$
- Substitute the values
If $n = 2$ moles, then the calculation will be:
$$ \text{Number of molecules} = 2 \times 6.022 \times 10^{23} $$
- Perform the multiplication
Now, perform the multiplication:
$$ \text{Number of molecules} = 12.044 \times 10^{23} $$
- Express in scientific notation
Lastly, convert the result into proper scientific notation if necessary:
$$ \text{Number of molecules} = 1.2044 \times 10^{24} $$
The total number of molecules in 2 moles of CO2 is approximately $1.2044 \times 10^{24}$ molecules.
More Information
This answer illustrates the conversion from moles to molecules using Avogadro's number, which is essential in chemistry for quantifying substances.
Tips
- Forgetting to multiply by Avogadro's number.
- Miscalculating the number of moles or using the wrong number.
- Confusing moles with the actual number of molecules.
