What is molality in Class 11?

Molality is defined as the “total moles of a solute contained in a kilogram of a solvent.” Molality is also known as molal concentration.

### What will be the molality of a solution of glucose in water which is 10 \% w/w a 0.01 m/c 0.668 m B 0.617 m/d 1.623 m?

Hence, the molality of the solution is 0.617m. Density of solution is 1.2 g mol L as per given in question.

What mass of Naoh is needed to produce 400g of a solution that is 12 by mass?

And so you want a 400⋅g mass of solution that is 12.0% BY MASS with respect to sodium hydroxide… i.e. mass of solute≡12%×400⋅g=48⋅g …and so this mass is dissolved in 352⋅mL≡352⋅g of water…….and this is what you surmised.

What is molality give example?

Molality is defined as the number of moles of solute present in 1000 gm of the solvent. For example, 1 molal NaOH solution means a solution with 1 mole of NaOH in 1 Kg water. Mathematically, molality(m)=number of moles of Solute(n)weight of the solvent in Kg. .

#### What is the molality of a solution which contains 18g of glucose in 250g of water?

Molality, m=M×Ww×1000=180×25018×1000=0. 4m.

#### What is the molality of a solution which contains 18g of glucose in 500g of water?

What will be the molality of a solution of glucose in water which is 10 \% w w?

0.617 m
Solution : 10 % by weight means that 10g of glucose is present in 100 g of solution . Mas of solvent `= 100- 10 = 90 g ` Moles of glucose `= (10)/(180) = 0.0556` Molality ` = (0.0556)/(90) xx 1000 = 0.617 m` .

What will be the molality of a solution having 18g of glucose dissolved in 500g of water?

## How do you calculate molality from molarity?

Molarity

1. Molarity: The molarity of a solution is calculated by taking the moles of solute and dividing by the liters of solution.
2. Molality: The molality of a solution is calculated by taking the moles of solute and dividing by the kilograms of solvent.

## What is the molarity of a solution that was prepared by dissolving 14.2 g of NaNO3 in enough water to make 350 mL of solution?

1. What is the molarity of a solution that was prepared by dissolving 14.2 g of NaNO3 in enough water to make 350 mL of solution? 14.26 Nallch imel NaNo – 0.167 moi.

What is molarity write formula?

The equation for calculating molarity is the ratio of the moles of solute whose molarity is to be calculated and the volume of solvent used to dissolve the given solute. M = n V.

What is the molality of a solution which contains 36g?

=(36g)(180 g mol-1)×(0.25kg)=0.8mol kg-1=0.8m.

### What is the molality of a solution which contains 36g of glucose?

1 Answer. =(36g)(180 g mol−1)×(0.25kg)=0.8mol kg−1=0.8 = ( 36 g ) ( 180 g mol – 1 ) × ( 0.25 k g ) = 0.8 mol kg – 1 = 0.8 m.
