Questions: 9.16 × 10^24 molecules of CO2

Transcript text: $9.16 \times 10^{24}$ molecules of $\mathrm{CO}_{2}$

Solution

Solution Steps

Step 1: Identify the Given Quantity

Given: $ 9.16 \times 10^{24} $ molecules of $ \mathrm{CO}_{2} $.

Step 2: Use Avogadro's Number

Avogadro's number is $ 6.022 \times 10^{23} $ molecules per mole.

Step 3: Calculate the Number of Moles

To find the number of moles, divide the given number of molecules by Avogadro's number: \[ \text{Number of moles} = \frac{9.16 \times 10^{24} \text{ molecules}}{6.022 \times 10^{23} \text{ molecules/mol}} \]

Final Answer

$\boxed{15.2 \text{ moles}}$
