b) How many moles of Na2O are required to produce 1.60 x 1024 molecules of NaOH?

Given the following equation: 8 Fe + S8 → 8 FeS
a) What mass of iron is needed to react with 16.0 moles of sulfur?

7148.16 grams of iron

Step-by-step explanation:

If you have 16 moles of S8, you have 16*8 moles of iron at 55.845 g/mol Iron. 16*8mol*55.845 g/mol leads moles to cancel and leaves you at 7148.16 grams of iron

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
