how many molecules are in 0.89 moles of ammonia
To determine the number of molecules in a given amount of substance, you can use Avogadro's number. Avogadro's number is the number of molecules in one mole of a substance, which is approximately 6.022 × 10^23.
To find the number of molecules in 0.89 moles of ammonia, you can use the following formula:
Number of molecules = moles of substance × Avogadro's number
Therefore, to find the number of molecules in 0.89 moles of ammonia, you would multiply 0.89 by Avogadro's number:
Number of molecules = 0.89 moles × 6.022 × 10^23 molecules/mole
Calculating the result:
Number of molecules = 5.35858 × 10^23 molecules
So, there are approximately 5.36 × 10^23 molecules in 0.89 moles of ammonia.
