Percent Yield Calculator
Compute the percent yield of a chemical reaction as the ratio of actual mass produced to the theoretical maximum.
Compute the percent yield of a chemical reaction as the ratio of actual mass produced to the theoretical maximum.
Compute the straight-line distance between two points (x₁, y₁) and (x₂, y₂) in 2D space.
Approximate the definite integral ∫ from a to b of f(x) dx with Simpson's 1/3 rule on a single interval, using f(a), f(m...
Calculates the RC time constant, voltage across the capacitor at time t, and charging current for a series RC circuit.
Computes y(t) = y₀ · e^(r·t) for continuous exponential growth (r > 0) or decay (r < 0). Also calculates the doubling ti...
Project population size at time t using the logistic model with intrinsic growth rate and carrying capacity.
Computes the first two convergents of a continued fraction from three partial quotients. Convergents are the best ration...
Compute the range (max − min), along with the minimum, maximum, and count of a list of numbers.
Calculates nPr = n!/(n−r)! (ordered arrangements) and nCr = n!/(r!(n−r)!) (unordered selections) for given n and r. Also...
Compute the fundamental frequency f₁ of a stretched string of length L, tension T, and mass-per-length μ. f₁ = (1/2L) ·...
Solve F = ma for any of force, mass, or acceleration — with unit-aware defaults.
Compute Chebyshev's inequality bound on the tail probability of any distribution with finite variance: P(|X − μ| ≥ k·σ)...
Every "X% of Y" problem, every "what percent of", every percent-change question — written out the way you'd actually say them.
Standard deviation is "average distance from the average". That one sentence covers 90% of everything you ever need to remember about it.
