Calculate pH, pOH, hydrogen ion concentration, and hydroxide ion concentration.
Find the degrees of unsaturation for any molecular formula with step-by-step val
Calculate molarity, moles, or volume using M = n/V. Enter any two values and sol
The calculator supports five operations: molar mass calculation for any chemical formula, molarity (concentration) calculations, stoichiometric conversions, chemical equation balancing, and pH/pOH calculations.
Yes! All chemistry calculations are completely free with step-by-step explanations. No account or sign-up required.
Enter any chemical formula (like H2O, NaCl, or C6H12O6) and the calculator breaks down each element's contribution to the total molar mass in g/mol.
Yes! Enter an unbalanced equation using -> or → to separate reactants and products. The balancer finds the smallest integer coefficients and identifies the reaction type.
Enter a hydrogen ion concentration, hydroxide ion concentration, pH, or pOH value, and the calculator computes all related values using pH = -log₁₀[H⁺] and pH + pOH = 14.
All calculations use deterministic algorithms and verified atomic mass data. Unlike AI chatbots, every result is mathematically guaranteed to be correct.
Enter a plain molecular formula such as C6H6. The calculator sums each element's bonding-valence contribution, applies DoU = 1 + (sum of n(v - 2))/2, cross-checks with (2C + 2 + N - H - X)/2, and lists every ring and pi-bond combination that fits.
Calculate allele and genotype frequencies using the Hardy-Weinberg equation with step-by-step solutions.
Calculate water potential, solute potential, and pressure potential for AP Biology using the Van't Hoff equation.
Calculate exponential and logistic population growth, doubling time, and carrying capacity with step-by-step solutions.
Generate the reverse complement of any DNA sequence, convert DNA to mRNA, and calculate GC content.
