How many particles are in 1.81 moles of PbCrO_(4) No answer text provided. No answer text provide). 1.09 particles 1.09^ast 10^24particles

To find the number of particles in 1.81 moles of $PbCrO_{4}$, we can use Avogadro's number, which is $6.022 \times 10^{23}$ particles per mole.<br /><br />First, we need to calculate the number of moles of $PbCrO_{4}$:<br />Number of moles = 1.81 moles<br /><br />Next, we multiply the number of moles by Avogadro's number to find the number of particles:<br />Number of particles = Number of moles × Avogadro's number<br />Number of particles = 1.81 moles × $6.022 \times 10^{23}$ particles/mole<br />Number of particles = $1.09 \times 10^{24}$ particles<br /><br />Therefore, there are $1.09 \times 10^{24}$ particles in 1.81 moles of $PbCrO_{4}$.
