Final answer:
To find the number of particles in 0.75 moles of AgNO3, multiply the number of moles by Avogadro's number. In this case, there are approximately 4.52 x 10^23 particles.
Step-by-step explanation:
To determine the number of particles in 0.75 moles of AgNO3, we need to use Avogadro's number, which is 6.022 x 10^23 particles per mole. Using this conversion factor, we can calculate:
Number of particles = Moles of AgNO3 x Avogadro's number
Number of particles = 0.75 moles x 6.022 x 10^23 particles per mole
Number of particles = 4.5165 x 10^23 particles
