because molality is independent of temperature and molarity is dependent on temperature further molality is dilute while molarity is concentrated.

0Concentrations in molality (moles of solute per kilograms of solvent) are independent of temperature and pressure whereas concentrations in molarity (moles of solute per total volume of solution in liters) are not.

if one scientist reports concentrations measured in molality, another scientist elsewhere can exactly replicate the work. This is not possible with molarity. I chose the above answer on my quiz and it was actually incorrect. The correct answer should be - two solutions of the same molality have equivalent ratios of solute to water, but two solutions of the same molarity may not have equivalent ratios.

Looks like someone is a bit lazy doing his/her homework... anyway: Molarity is the number of moles present in a volume of 1 litre. (Moles/L) Molality is the number of moles present in 1 kg of solution. (Moles/Kg) Density, is mass per volume. (should be in Kg/L) First think intuitively. MolaRity = molaLity when 1 L is the same amount of matter than 1 Kg. That's when the density of the solution is 1 Kg/L. If the solution is more dense, then the same volume holds more mass, so MolaRity > molaLity. This relation is proportional to the density, so... you can work out the formula. Another way of looking at the problem is doing dimensional analysis (some call it cheating... it's that great!): You need Moles/L and you have two magnitudes expressed in Moles/Kg and Kg/L. The only way you can cancel out those Kg is by simply multiplying them: Moles/Kg x Kg/L = Moles/L Molality x density = Molarity Voila! problem solved

Probably molality (note: this is not a typo). Molality is the number of moles of solute per kilogram of solvent, and is not widely used except in equations dealing with colligative properties. Remember, molality is moles of solute/kg of solvent. It is always clear if you get this value correct because molality is ALWAYS higher than molarity. (This answer has been updated.)

Metric units have many advantages over Imperial units but precision and accuracy are not amongst them. Precision and accuracy depends on the individual units in use. For example, A kilometre is more accurate than a mile, A furlong is more accurate than a kilometre, A metre is more accurate than a kilometre, A yard is more accurate than a metre, A foot is more accurate than a metre, An inch is more accurate than a foot, A centimetre is more accurate than an inch, A thou is more accurate than a centimetre, and so on, and on.

Yes, and for many solutions it often is.

If the volume of the titrant is between that range, it takes out the mainstream of error. It is allowed to be more accurate when determining mols and molarity of the compounds within the titrations

A concentrated acid has more acid than water and a dilute acid has more water than acid. True facts, otherwise known as its molarity. The greater the molarity the more concentrated it is (moles of acid/ liter of solution)

they did, actually it is more accurate than ours!

More accurate than what?

Knowing the molarity is more meaningful because by knowing it you can not only know if it is diluted or concentrated, but also the actual concentration.

Yes, for they are simply more accurate and on point.

It is more accurate, a 4 wire is more accurate than 3 wire and 3 wire is more accurate than 2 wire.

The more accurate number - is 1.005 - as it is accurate to more decimal places than the other examples.

Pretty freakin accurate; more accurate than a urine test!

Usually more accurate than the shooter

Within a set volume of solvent (usually water), a concentrated solution will have more solute than a diluted silution. In chemistry, this is called molarity. The more moles of solute you have in solution, the higher the concentration, or molarity of that solution. Molarity is defined as moles solute/liter solvent, and is abbreviated "M".

Because as humans have explored the world more and more maps are getting more and more accurate.

There is no more accurate descriptions of matter than measurements. To get the description right make your measurements precise.

Aggregated forecasts are more accurate than individual product forecasts.

This isn't always the case; however, millimeters are more accurate than centimeters when you want to measure smaller things.

The pycnometer method is more accurate than the hydrometer method because it uses an analytical balance.

The term for a level of solutes in a solution is called the concentration. A "concentrated" solution has more solutes than a "dilute" solution.There are two related terms:The molarity or molar concentration expresses the mass of constituents per volume of solution.The related term molality expresses the mass of constituents per mass of solvent.

Weather forecasts are more accurate today than in the past due to the use of images from space.

Because the smaller the cylinder the more accurate the measurement.
