How many molecules and moles of sulfur are in 6.4g of S04?
- Simonizer1218Lv 75 years ago
Let's assume you mean SO4^2- (sulfate anion):
molar mass of SO4^2- = 96 g/mol
6.4 g x 1 mol/96 g = 0.067 moles SO4^2-
moles Sulfur: 0.067 moles SO4^2- x 1mol S/mol SO4^2- = 0.067 moles sulfur
0.067mole x 6,02x10^23 atoms/mole = 4.0x10^22 S atoms
