How do you explain molarity?

Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution.Apr 29, 2020

What is molarity in mole concept?

Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution. Molarity can be used to calculate the volume of solvent or the amount of solute.

Which is temperature dependent molarity or molality and why?

Molarity is dependent on temperature, whereas molality is not. With temperature, molarity varies. Molarity is solute moles per litre of solution. As the temperature increases, water expands, so the solution's volume therefore increases.

What is the molarity of NaOH?

The molarity of NaOH is 2.002 x 10 -2 moles x 1000 mL/L / 25.0 mL = 0.801 Molar.Dec 11, 2020

What is class 11 molarity?

Molarity, which is denoted by 'M' is defined as the number of moles of solute in per litre solution and its unit is (moles/litre) which is one of the most common units which is used to measure the concentration of solution.

What is molarity example?

Molarity=moles of solutelitres of solution. For example, a 0.25 mol/L NaOH solution contains 0.25 mol of sodium hydroxide in every litre of solution. To calculate the molarity of a solution, you need to know the number of moles of solute and the total volume of the solution.May 22, 2014

How do you convert molarity to molality?

Find the total mass of the solution.Multiply 1 L X the density (1.84 g/mL) X 1000 mL/L. ... Calculate the grams of the solute.18M means 18 moles of sulfuric acid per one liter of solution.More items...

Why molarity is affected by temperature?

As molarity is dependent on volume (mol/L) and volume rises as temperature does, molarity is inversely proportional to temperature. As temperature increases, volume also increases, which means that it will decrease the number of moles per litre. So, molarity decreases as the temperature increases.

Which one is more preferable molarity or molality?

So, the molarity is function of volume which can be affected by changing the temperature of system while the molality of system is function of mass which does not have any effect of temperature. So, the molality is preferred over the molarity to express the concentration of a solution.

Why molarity is independent?

Molarity depends on temperature. It is Molality which is independent of temperature. Molarity(M)= Number of moles(n) of solute/Volume of solution (V) in litres. Since,V depends on temperature(T),thus M depends on T.
