 # Question: Is Urea Non Volatile?

## What is the molecular mass of urea?

60.06 g/molUrea/Molar mass.

## How many grams of nonvolatile solute have a molecular weight of 90?

Thus 12.5 grams of non volatile solute having a molecular weight of 90 are to be dissolved in 97.5 g water in order to decrease the vapor pressure of water by 2.5 percent.

## Is urea a non volatile solute?

What mass of non-volatile solute (urea) needs to be dissolved in `100 g` of water in order to. What mass of non-volatile solute (urea) needs to be dissolved in `100 g` of water in order to decrease the vapour pressure of water by `30%`.

## What is the weight of a non volatile solute?

Hence the weight of non-volatile solute reqired is 5gm.

## Where is urea used?

Urea is widely used in the agricultural sector both as a fertilizer and animal feed additive. The main function of Urea fertilizer is to provide the plants with nitrogen to promote green leafy growth and make the plants look lush. Urea also aids the photosynthesis process of plants.

## What is the weight of a non volatile solute of molar mass 40?

Calculate the mass of a non-volatile solute (molar mass 40 g mol-1) which should be dissolved in 114 g octane to reduce its vapour pressure to 80%. Let the vapour pressure of pure octane be p10. Then, the vapour pressure of the octane after dissolving the non-volatile solute is 80/100 p10 = 0.8 p10.

## Is sucrose volatile or non volatile?

Raoult’s Law When you have a non-volatile solution, such as a sucrose or salt solution, you have an increasing boiling point as the concentration of sucrose or sugar increases.

## What is the mass of non volatile solute urea?

What mass of non-volatile solute (urea) needs to be dissolved in 100 g of water in order to decrease the vapour pressure of water by 25%.

## What weight of the nonvolatile solute urea needs to be dissolved in 100 g of water in order to decrease the Vapour pressure of water by 25 %? What will be the molality of the solution?

Answer. W2 = ? Therefore, 83.33 g of urea is required to lower the vapour pressure.

## What is non volatile urea weight?

A non volatile, non-electrolyte solid whose weight is 2. 75gm, is added to 39.
