Problem
Find the area enclosed between y = x² and y = 2x in the first quadrant.
1
Find the points of intersection
Set the curves equal: x² = 2x → x(x - 2) = 0, so x = 0 and x = 2.
2
Identify which curve is on top
On (0, 2), 2x > x², so y = 2x is the upper curve.
3
Set up the area integral
A = ∫₀² (2x - x²) dx
4
Integrate term-by-term
A = [ x² - x³/3 ]₀²
Final Answer
A = 4/3 sq. units
Quick Answer
What is stoichiometry?
Stoichiometry uses the balanced equation of a reaction to compute amounts of reactants and products. Coefficients give mole ratios. To go from grams of one substance to grams of another: convert grams to moles using molar mass, apply the mole ratio, convert moles back to grams. For limiting reagent problems, compute moles of product each reactant could produce; smallest is the actual yield and the corresponding reactant is limiting.

Step 02
AskSia picks the method.
Based on the problem structure, AskSia chooses the cleanest solution path and labels each step with the operation performed.
1
Set curves equal
x² = 2x → x = 0, x = 2
2
Set up the integral
A = ∫₀² (2x - x²) dx
3
Evaluate
A = [x² - x³/3]₀² = 4/3
Step 03
Read the verified answer.
Final result appears with a substitution or composition check. Practice problems on the same concept are one tap away.

FAQ
Frequently asked questions.
What is a mole ratio?
The ratio of moles of one substance to moles of another from the balanced equation, read directly from the coefficients. For 2H2 + O2 -> 2H2O, the mole ratios are 2:1:2.
How do you find the limiting reagent?
Convert each given mass to moles. For each reactant, compute moles of product it could form. The reactant producing the smallest is the limiting reagent.
What is percent yield?
Percent yield = (actual/theoretical) * 100. Theoretical is what stoichiometry predicts. Actual is measured in lab; usually less due to losses, side reactions, or incomplete reactions.
How is gas-volume stoichiometry handled?
At STP (0 C, 1 atm), 1 mole of gas occupies 22.4 L. For non-STP, use PV = nRT. AskSia handles both based on conditions.
How accurate is AskSia?
AskSia is engineered for accuracy on standard high school and college coursework. Accuracy comes from subject-specialized models, a symbolic verification pass that catches arithmetic errors, and a self-check step that re-derives the answer before showing it to you.
Can I get practice problems and flashcards?
Yes. After any solve, ask Sia to generate similar practice problems at SAT, ACT, AP, IB, or college difficulty, or build a flashcard set on the underlying concept in one tap. Useful for exam prep and spaced repetition before a quiz, midterm, or final.
How much does AskSia cost?
AskSia has a free plan that includes daily solves across all subjects. AskSia Pro and Super include unlimited solves, advanced subjects, the full AI tutor companion, exports, and priority response speed. See pricing for details.
