Calculation Tools for Researchers
Accurate quantitative analysis is central to chemistry research. The following free online tools support common calculations encountered in laboratory work and data analysis at DChy, PIEAS.
-
Percent Yield Calculator
— Determine the efficiency of a chemical reaction by calculating percent yield from actual and theoretical yield values. Directly applicable to synthetic chemistry and radiopharmaceutical preparation workflows.
-
Molarity Calculator
— Calculate molar concentration from solute mass, molar mass, and solution volume. Useful for preparing reagent solutions and stock concentrations required in experimental protocols.
-
Linear Regression Calculator
— Compute the best-fit line through experimental data points using least squares fitting. Widely used in analytical chemistry for calibration curves, concentration-absorbance relationships, and quantitative data interpretation.
-
Density Calculator
— Compute density, mass, or volume using ρ = m/V across multiple unit systems. Applicable to material characterisation, polymer composite studies, and physical property measurements.
