A solution is prepared by dissolving 27.0 g of urea [(NH2)2CO], in 150.0 g of water. Calculate the boiling point of the solution. Urea is a nonelectrolyte.

The boiling point of solution is 101.56°C

Explanation:

Elevation in boiling point is defined as the difference in the boiling point of solution and boiling point of pure solution.

The equation used to calculate elevation in boiling point follows:

To calculate the elevation in boiling point, we use the equation:

Or,

where,

Boiling point of pure water = 100°C

i = Vant hoff factor = 1 (For non-electrolytes)

= molal boiling point elevation constant = 0.52°C/m.g

= Given mass of solute (urea) = 27.0 g

= Molar mass of solute (urea) = 60 g/mol

= Mass of solvent (water) = 150.0 g

Putting values in above equation, we get:

Hence, the boiling point of solution is 101.56°C

s too much pool water may lead to chlorine poisoning. the concentration of chlorine in public drinking water is extremely low and not harmful to human health. sooo yeahh

explanation:

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
