How many moles are in 5.15times 10^22 particles of LiOH? 8.55molecules 8.55 mol 0.0855 molecules 0.0855 mol

To determine the number of moles in $5.15\times 10^{22}$ particles of LiOH, we need to use Avogadro's number, which is $6.022\times 10^{23}$ particles per mole.<br /><br />Given:<br />Number of particles of LiOH = $5.15\times 10^{22}$<br /><br />To find the number of moles, we divide the number of particles by Avogadro's number:<br /><br />Number of moles = $\frac{5.15\times 10^{22}}{6.022\times 10^{23}}$<br /><br />Calculating this gives us approximately 0.0855 moles.<br /><br />Therefore, the correct answer is 0.0855 mol.
