## What is molality of a solution?

The molality ( m ) of a solution is the moles of solute divided by the kilograms of solvent.

A solution that contains 1.0 mol of NaCl dissolved into 1.0 kg of water is a “one-molal” solution of sodium chloride.

The symbol for molality is a lower-case m written in italics..

## What is the molality of a solution containing 200 mg of urea dissolved in 40 gram of water?

What is the molality of a solution containing 200 mg of urea (molar mass 60 g mol-1) dissolved in 40 g of water? 0.0825.

## How do you calculate Molality?

The formula for molality is m = moles of solute / kilograms of solvent. In problem solving involving molality, we sometimes need to use additional formulas to get to the final answer. One formula we need to be aware of is the formula for density, which is d = m / v, where d is density, m is mass and v is volume.

## What is the molality of a solution containing 200 mg of urea?

What is the molality of a solution containing 200 mg of urea (molar mass =60gmol-1) ? =0.0825mol Kg-1=0.0825m .

## What is the molality of the solution containing 18.25 g of HCl gas in 500g of water?

What will be the molality of the solution containing 18.25 g of HCl gas in 500 g of water? Molality of solution is 1 m.

## What is the difference between molarity and molality?

An important distinction between molality and molarity is the difference between a solution and a solvent. Molarity is the ratio of the moles of a solute to the total liters of a solution. … Molality, on the other hand, is the ratio of the moles of a solute to the kilograms of a solvent.

## What is the molarity of a solution that contains 30 g of NaOH in 500 ml of solution?

Answer: 1.5 M. 30g sample= 0.75 mole.

## What is the molality of a solution of methanol in water?

75 moles has a mass of (0.75×18. 02) =13.52 g or . 01352 kg. Now, molality is defined as moles of solute divided by kg is solvent.

## When 10g of Naoh is dissolved in 500g of water calculate the molality of the solution?

1 Answer. Ernest Z. The molality is 0.50 mol/kg.
