Question

How man molecules are in 0.500 mole of lactic acid?

Answer 1

There are approximately 3.011 x 10^23 molecules in 0.500 mole of lactic acid.

Step-by-step explanation:

To determine the number of molecules in 0.500 moles of lactic acid, we can use Avogadro's number. Avogadro's number is approximately 6.022 x 10^23 molecules/mol.

So, for 0.500 mole of lactic acid, we can multiply it by Avogadro's number to find the number of molecules:

Number of molecules = 0.500 mol x 6.022 x 10^23 molecules/mol = 3.011 x 10^23 molecules

Therefore, there are approximately 3.011 x 10^23 molecules in 0.500 mole of lactic acid.
