(in liters). The prefix "milli-" indicates "1 thousandth," that is, the magnitude of 0.001 (see Resources). Hence, 1 mole is equal to 1 millimoles multiplied by 1,000. As an example, calculate concentration in millimolars if 0.5 grams of sodium hydroxide (NaOH) were dissolved in 500...
This relates to the fact that chemicals react with each other not on the basis of mass but on the basis of the ratio of individual "pieces," regardless of size. The concept of moles and equivalents, and thus millimoles and milliequivalents, underlies this relationship, and it is of vital...
The molarity of a solution is the concentration of the solution in terms of the number of moles per liter of solution. This expression of the concentration is quite convenient since we can determine the number of moles of a solute when we know the volume of the solution. This ease...
Your doctor will use this information to calculate your 10-year risk for serious heart problems. The more risk factors you have, the higher your risk of heart problems and stroke. Taking steps to reduce them, including lowering cholesterol, may also help reduce other risk factors you have. ...
Calculate the molarity of a 5% glucose solution. How many grams of glucose (C6H2O6 molecular mass=180 daltons) would be present in one liter of a 1M (molar) solution of glucose? To prepare a 248 mM sugar solution, how many sugars (molecular weight = 309 g/mo...
If you see "normal" as "expected," even in the chemical sense this is more or less on target: A normalized preparation is one that has been created in proportion or relation to an established standard. To discover how to calculate the normality of NaOH, or how to convert from normality ...
Then, for xmolL of the compound will yield (a×x) number of moles for ion A and (b×x) number of moles for ion B per 1 liter of the solution. This means, the concentration of ion A is equal to axmolL the concentration of ion B is equal to bxmolL ...
But the units are no longer moles/L, but rather millimoles/L or mmol/L. These units are called millimolar or mM. While in many cases scientists prefer to talk about concentration in terms of molarity, it can sometimes be more useful to talk about mass per liter solvent. For example, ...
Calculate Molarity: moles solute per liter of solution (notvolume of solvent added since the solute takes up some space) symbol: M M = moles / liter Example: What is the molarity of a solution of 6 grams of NaCl (~1 teaspoon of table salt) dissolved in 500 milliliters of water?
Learning how to calculate molarity isn't difficult; the key is to remember the units of molarity (M): moles per liter. Find the molarity by calculating the number of moles of the solute dissolved in liters of a solution. Molarity is a unit of concentration, measuring the number of moles ...
