Final answer:
There are approximately 3.37 × 10^23 NH3 molecules in 0.56 moles, calculated by using Avogadro's number.o find the number of molecules in 0.56 moles of NH3, multiply the number of moles by Avogadro's number.
Step-by-step explanation:
To determine the number of molecules in 0.56 moles of NH3, you can use Avogadro's number, which is 6.022 × 1023 molecules per mole. The number of molecules in 0.56 moles of NH3 can be calculated by multiplying the number of moles by Avogadro's number:
Number of NH3 molecules = 0.56 moles × 6.022 × 1023 molecules/mole
You'll find that there are approximately 3.37 × 1023 NH3 molecules in 0.56 moles.
