Answer :
Final answer:
To convert grams of NH₃ to particles, divide the given mass by the molar mass to find the number of moles. Then, multiply the number of moles by Avogadro's number to calculate the number of particles.
Explanation:
To convert grams of NH₃ to particles, we need to use the concept of Avogadro's number. Avogadro's number is 6.022 x 10^23 particles per mole. First, we need to convert grams of NH₃ to moles by dividing the given mass by the molar mass of NH₃. The molar mass of NH₃ is 17.03 g/mol. In this case, we have 35.5g NH₃, so the number of moles is 35.5g / 17.03 g/mol = 2.09 moles of NH₃. Finally, multiply the number of moles by Avogadro's number to calculate the number of particles: 2.09 moles NH₃ * 6.022 x 10^23 particles/mol = 1.26 x 10^24 particles.
