Answer 1

Answer on Question #109610, Chemistry, General Chemistry

9.50*10^22 formula units of lead (II) nitrate is how many moles?

Solution:

Number of moles of lead (II) nitrate can be determine as:

n (Pb(NO₃)₂) = N/Na, where N = 9.50*10²²; Na is Avogadro's number which equals 6.022*10²³ mol^-1.

Thus:

n (Pb(NO₃)₂) = 9.50*10²²/6.022*10²³ = 0.158 (moles)

Answer: n (Pb(NO₃)₂) = 0.158 moles.
