Answer:
moles of calcium hydroxide= 21.75 mol
a) 43.5 mol
b) 7.25 mol
Explanation:
Please see the attached picture for the full solution.
Answer:
35.453 atomic mass units
You can use Phet (Atomic masses, Elements and more) for Chemistry
Mass of SO2 = mass of sulfur+ mass of oxygen
⇒ 64 g= mass of sulfur+ 32 g
⇒ mass of sulfur= 64 g-32 g
⇒ mass of sulfur= 32 g.
There is 32 g of sulfur in 64 g of SO2~
