Answer:
3.55 x 10²⁴ molecules
Step-by-step explanation:
Data Given:
moles of propane = 5.9 moles
molecules of propane (C₈H₈) = ?
Solution
Formula will be used
no. of moles = no. of molecules / Avogadro's number
Rearrange the above equation:
no. of molecules = no. of moles x Avogadro's number . . . . . (1)
Where
Avogadro's number = 6.022 x 10²³
Put values in equation 1
no. of molecules =5.9 mol x 6.022 x 10²³ (molecules/mol)
no. of molecules = 3.55 x 10²⁴ molecules
So,
There are 3.55 x 10²⁴molecules in 5.9 moles of propane
