This page holds a finished CHEM-110 Week 5 stoichiometry calculation: one worked problem in labeled stages, with the ratio taken from a balanced equation printed above it. Searches like "chem 110 week 5 assignment example", "chem110 week 5 sample" and "chem-110 week 5 example" land here.
What a finished CHEM-110 Week 5 stoichiometry calculation looks like
One worked problem set out in four labeled stages down the page, not a paragraph with figures buried in it. The balanced equation sits at the top with the two compounds that matter marked, because every ratio used below is read off it. Stage one converts the given mass into an amount and names the molar mass it used and the compound that molar mass belongs to. Stage two crosses to the other compound using the coefficients, written as a ratio with both names in it. Stage three converts back into whatever measure was asked for. A closing line states the result with its compound and says which stage would move it if the equation were wrong.
How a CHEM-110 Week 5 example is structured
Four stages, and the example labels every one of them rather than letting the reader infer the boundaries. The balanced equation is reproduced first, even when the week supplied it, so the ratio below has a visible source. The first conversion follows and is explicit about which compound its molar mass came from, since both compounds in the problem have one and they are not interchangeable. The crossing comes third and is written as a sentence as well as a factor, naming both compounds, because this is the only stage the rest of the course was building toward. The final conversion returns to the measure the question asked for. The closing line reports the result and attaches the compound to it, then says in a clause what the figure is a figure of.
The equation goes on the page
Reproduce the balanced equation above the working even when the week supplied it. Every ratio underneath is read off it, and a ratio with no visible source earns nothing.
Name the compound on each molar mass
Both compounds in the problem have one, and they differ. Saying which compound a molar mass belongs to is what stops the two being swapped without anyone noticing.
The crossing is the assignment
The move between one compound's amount and another's is the only stage that needed the equation. Write it as a sentence with both names as well as a factor.
Return to what was asked
The final conversion lands in the measure the question wanted. A correct amount reported in the wrong measure loses the closing row and reads as an unfinished problem.
Stages carry labels
Four labeled stages down the page let a marker award three of them when the fourth goes astray. A continuous paragraph makes that impossible to do.
Where marks go in CHEM-110 Week 5
Nothing drains this week faster than a calculation relating two masses directly, with the crossing performed in somebody's head, because the stage the assignment was built around has then left no trace. Next in cost is a ratio read off the wrong pair of coefficients, which returns a clean figure of the wrong size and looks entirely ordinary. A molar mass worked out for the wrong compound at one end produces the same kind of wrongness. Where the balanced equation is missing from the page, the ratio has no source and the sourcing row goes empty even if the ratio is right. And a result reported in the measure the question gave rather than the one it asked for loses the closing row.

CHEM-110 Week 5 questions, answered
Do I have to show the molar mass being worked out?
Show at least the total and which compound it belongs to. Whether the arithmetic behind it appears depends on your section, and some rubrics carry a row for it. What cannot be left out is the attachment: a molar mass floating in the working with no compound named beside it is the single easiest place for the two compounds in a problem to swap without any of the measures objecting.
The question gives a quantity nobody uses. Is that a mistake?
Usually it is deliberate, and saying so in one clause is worth points. Assignments include a figure that plays no part to see whether the route was chosen or reached for. Name the unused quantity, say why the route did not need it, and move on. Spending a paragraph on it, or bending the working to consume it, both cost more than leaving it unmentioned would have.
How many figures should the final result carry?
Take the convention from your section, and where none is published, let the least precise quantity you were given govern and say in a clause that it did. What earns the row is that the decision is visible on the page rather than which convention was followed. Carry everything through the stages at full precision and settle it once, in the closing line.
