To find the number of molecules in 3 mol of C3H8, we can use Avogadro's number. Avogadro's number is approximately 6.022 x 10^23 molecules per mole.
So, to calculate the number of molecules in 3 mol of C3H8, we multiply 3 mol by Avogadro's number:
3 mol * 6.022 x 10^23 molecules/mol = 1.8066 x 10^24 molecules
Therefore, there are approximately 1.8066 x 10^24 molecules in 3 mol of C3H8.
Let me know if there's anything else I can help with!
