mole × molecular weight = mass (rearrange the equation) mass = molecular weight × mole As 1.626×1023 molecules of NaOH is also equal to 0.27 moles, and we know that the molecular weight of NaOH is 40, we can use these numbers to get: mass = 40 × 0.27 = 10.8 g So we now know...
Learn about the mole ratio. Understand the definition of mole ratio, how to find mole ratio in stoichiometry, and see examples of using mole ratio...
Mole, standard unit (6.02214076 x 10^23) in chemistry for measuring large quantities of very small entities such as atoms, molecules, or other specified particles. The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s const
Therefore it is generally desirable to match the concentration of the fluid within the target area in the body, such as blood, to the concentration of the medication. A patient receiving medication from an IV bag on a pole. A note on conversion between molarity and osmotic co...
aThe mole fractions determination compensated by the thermal responses was performed by calculating the percentage of the total area as shown in equation above: 热量反应补偿的克分子分数决心通过计算总面积的百分比进行如等式所显示上面:[translate]
The fundamental concept of the mole stems from the idea of the gram-atom (or gram-molecule): that an amount of one mole of a given substance has an associated mass, in grams, numerically exactly equal to the relative atomic (or molecular) mass of the substance. This means that the parti...
Various interpretations of what a mole actually means and how this affects the ideal gas equation depend on how the amount of a given substance, n , is related to the corresponding number of entities, N . We look at three alternatives: (1) the conventional interpretation in which n is ...

Mole ratio units are either mole:mole or else it is a dimensionless number because the units cancel out. For example, it's fine to say a ratio of 3 moles of O2to 1 mole of H2is 3:1 or 3 mol O2: 1 mol H2. Mole Ratio Example: Balanced Equation ...
