molar1
/ˈməʊlə
/- The location of early caries is found most often in children's maxillary incisors and first molars.
- The medical name for wisdom teeth is the third molars.
Origin
Late Middle English: from Latin molaris, from mola 'millstone'.
mill from Old English:
Early mills ground corn into flour using water or wind power. The root of mill is Latin molere ‘to grind’, also the source of meal ‘the edible part of any grain or pulse’, and molar (Middle English) the grinding tooth. Since the early 19th century people have been able to put someone through the mill, or cause them to have a difficult experience. A millstone (Old English) is a large circular stone used to grind corn. The origins of a millstone around your neck, ‘a heavy burden of responsibility’, lie in a far more unpleasant practice. It is thought to come from an ancient method of execution which involved throwing a person into deep water with a heavy stone attached to their neck.
Rhymes
molar2
/ˈməʊlə/- He couldn't even find the molar mass of water.
- The experiments with the solids mostly involve oxidation reactions, measuring the water of hydration, and finding the molar mass by titration.
Origin
Mid 19th century: from Latin moles 'mass' + -ar1.
molar3
/ˈməʊlə/- Uncharged polar and even ionic dyes with substantial molar weights have often been used to trace apoplastic water movement.
- Another substantial advantage is that volume fractions and molar concentrations are easily interconvertible, making comparison with experimental papers easier.
- An example of this would be describing a solution as a 1 molar solution, or saying it had a strength of 1 M.
- In this case a solution that was 0.9 molar in trehalose and sucrose was examined for a sample at known spacing as described for water.
Derivatives
molarity
- If the solvent used is water the molarity and the molality are essentially the same.
- The titrated volume and molarity of the base can be used to determine the acid concentration.
- The absolute molar concentration was such that when dissolved in the final volume of aqueous buffer the solution had a total lipid plus cholesterol molarity of 2 mM.
