C1·V1 = C2·V2 holds only when the units match on both sides. This page converts everything to mol/L first, which needs a molecular weight for the mass-based units and a density for v/v. A v/v figure without a density is a volume ratio, not a concentration, and is only equivalent to mol/L if the density is exactly 1 g/mL. For % w/v, 1% is 1 g per 100 mL, i.e. 10 g/L. A serial ladder compounds the same factor every step and never dilutes to zero.
Conduction, convection and Stefan-Boltzmann radiation in series and in parallel, solving for Q, thickness, k, h, emissivity or area. The series case iterates the radiation term at the unknown surface temperature instead of summing a resistance that is not constant, and air at 0.026 W/(m K) is in the table.
Pipe flow from ID and velocity, or solved from a pressure drop and length with an iterated Colebrook-White friction factor alongside the explicit Swamee-Jain and Haaland approximations and the gap between them. Separates laminar, transition and turbulent regimes and says where the equations stop being reliable.
Independent, paired and one-sample t-tests from real summary statistics: the t statistic, degrees of freedom, p-value and a verdict at alpha 0.05.
