To find the number of molecules in 0.25 moles of carbon tetrachloride (CCl4), we can use Avogadro's number, which is 6.022 x 10^23 molecules/mol. This number tells us how many molecules are in one mole of a substance.
Here are the steps we'll follow:
1. Identify the number of moles given: 0.25 moles of CCl4. 2. Recognize that Avogadro's number is 6.022 x 10^23 molecules per mole. 3. Multiply the given number of moles by Avogadro's number to find the total number of molecules.
Calculation: Number of molecules = number of moles × Avogadro's number Number of molecules = 0.25 moles × 6.022 x 10^23 molecules/mol
Number of molecules = 1.5055 x 10^23 molecules
So, there are approximately 1.5055 x 10^23 molecules of carbon tetrachloride in 0.25 moles.
