I think the answer is C. Runoff hopefully this helps
Answer:
Percent yield = 90.8%
Explanation:
The reaction of Fe with S to produce FeS is:
Fe + S → FeS
<em>Where the moles of Fe added in excess of S are the moles of FeS</em>
<em />
Now, percent yield is defined as 100 times the ratio between actual yield (13.8g of FeS) and theoretical yield (15.2g FeS):
Percent yield = 13.8g / 15.2g * 100
<h3>Percent yield = 90.8%</h3>

245 mm Hg = 32.6634 kPa
<u>Explanation:</u>
When the pressure inside the can is measured in mm Hg and it is needed to convert mm mercury (Hg) to kilo pascal, we have to multiply the pressure in mm Hg with 0.13332, so that the pressure is converted in kilo pascals.
1 mm Hg × 0.13332 = 1 kPa
245 mm Hg × 0.13332 = 32.6634 kPa
So the pressure in mm mercury is converted into kilo pascals.
