Answer:
A
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the base radius and h the height )
Here r = 6 and h = 8, then
V = π × 6² × 8 = π × 36 × 8 = 288π cm³ → A
It's incorrect. There are 6 moles of NaBr produced for every 3 moles of Na₂S among the reactants (as well as 2 moles of FeBr₃), so the mole ratio of NaBr to Na₂S should be 2 : 1, not 1 : 1.
