Question

How many moles are present in 3.45 x 10⁵ molecules of CH?​

Answer 1

To find the number of moles in 3.45 x 10⁵ molecules of CH, divide the given number of molecules by Avogadro's number (6.022 x 10²³ molecules/mol). The answer is 5.73 x 10⁻¹⁹ mol.

Step-by-step explanation:

To find the number of moles in 3.45 x 10⁵ molecules of CH, we need to use Avogadro's number as a conversion factor. Avogadro's number is 6.022 x 10²³ molecules/mol. So, to convert the number of molecules to moles, divide the given number of molecules by Avogadro's number:

3.45 x 10⁵ molecules of CH x (1 mol/6.022 x 10²³ molecules) = 5.73 x 10⁻¹⁹ mol
