Solution Preparation
M | N | PPM | PPB | Purity | Auto Density
e.g., HCl=1, H₂SO₄=2
If not 100% pure (e.g., 95%)
Molarity (with Purity)
%
Example: 5.844g NaCl (MW 58.44) in 1L → 0.1 M
Molality (m)
Example: 5.844g NaCl in 1kg water → 0.1 m
Dilution C₁V₁=C₂V₂
Example: C₁=1M, C₂=0.1M, V₂=100mL → V₁=10mL
% Solution
Example: 5% w/v in 100mL → 5g solute
PPM/PPB Converter
Example: 50mg in 2L → 25,000 ppm
