Answer :
Final answer:
The number of particles in 3 moles of a substance, like boron, is obtained by multiplying the number of moles (3) by Avogadro's number (6.022 x 10^23). So we find there are approximately 1.8066 x 10^24 particles in 3 moles of boron.
Explanation:
To answer this question, we have to multiply the number of moles by Avogadro's number. Avogadro's number, which is 6.022 x 1023, is the number of particles in one mole of a substance. Hence, if we have 3 moles of any substance, including boron, we would have 3 times Avogadro's number of particles.
To find the total number of particles in 3 moles of boron, you would calculate: 3 moles x 6.022 x 1023 particles/mole = 1.8066 x 1024 particles.
So, there are approximately 1.8066 x 1024 particles in 3 moles of boron.
