Molality slider animation — m = (1000·w) / (Mr(100−w))
Use the sliders to change mass % (w) and molar mass (Mr). Hit play to animate the w sweep and watch molality update in real time.
Formula (mass % → molality):
m = 1000·w / (Mr · (100 − w))
Substituted:
m = — / (—) =
— mol·kg⁻¹
Current values
Molar mass 180.0 g·mol⁻¹
Mass % 10.0 %
Molality
— mol·kg⁻¹
Notes:
- Formula:
m = 1000·w / (Mr·(100−w))where w is mass % (g solute per 100 g solution). - Set molar mass and watch how molality rises as w → 100% (denominator → 0).
