Answer:
The correct answer is 2, 0M
Explanation:
We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case NaCl) in 1000ml of solution (1 liter):
250 ml solution----- 0,5 moles of NaCl
1000 ml solution----x= (1000 ml solution x 0,5 moles of NaCl)/250 ml solution
x= 2,0 moles of NaCl --> <em>The solution is 2 M</em>
120 Fahrenheit -32 x 5/9 +273.15 = 322
Sorry this is long, it’s the best I’ve got. The name was chosen based on the time of year (around December) during which these warm waters events tended to occur. The term El Niño refers to the large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific. The term El Niño refers to the large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific. The vast tropical Pacific Ocean receives more sunlight than any other region on Earth. Much of this sunlight is stored in the ocean in the form of heat. During an El Niño water temperatures in the Pacific Ocean may rise on average 3 - 5 degrees above average
Answer:
The answer to your question is 68.8%
Explanation:
Data
Iron = 3.8 moles
Sulfur = excess
FeS = 230 g
Molecular weight FeS = 88 g
Process
Reaction
Fe + S ⇒ FeS
1.- Convert the number of moles of Iron to grams
56 g of Iron -------------- 1 mol
x -------------- 3.8 moles
x = (3.8 x 56) / 1
x = 212.8 g of Iron
2.- Calculate the theoretical production of FeS
56 g of Iron ---------------- 88 g of FeS
212.8 g of iron ----------- x
x = (212.8 x 88) / 56
x = 334.4 g of FeS
3.- Calculate the percent yield
% yield = 
% yield = 68.8
