Step-by-step explanation:
To find the number of molecules of H2O produced when you have 0.827 moles, you can use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole. Here's how you calculate it:
Number of molecules = (Number of moles) x (Avogadro's number)
Number of molecules = 0.827 moles x (6.022 x 10^23 molecules/mole)
Number of molecules ≈ 4.98 x 10^23 molecules
So, approximately 4.98 x 10^23 molecules of H2O are produced.
