n - mole Pb(SO4)2 , C concentration solution - 0.6554 M (mole/L), V - volume solution 225mL=0.225L,
n= V*C=0.225L * 0.6554 mole/L = 0,147465 mole == 0.1475 mole
m - weight (mass, g) Pb(SO4)2 ; Molar [mass] Pb(SO4)2 =399.3 g/mole
m=n * Molar = 0.1475 mole * 399.3 g/mole = 58,89675 g == 58,90 g
Answer: 58,90 grams of lead (iv) sulfate are in 225.0 mL of a 0.6554 M solution
