<u>Answer:</u> The boiling point of solution is 101.56°C
<u>Explanation:</u>
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
The neutrino is the particle that cannot be accelerated in a
magnetic field.
To add, a neutrino is a subatomic particle that is
very similar to an electron, but has no electrical charge and a very small
mass, which might even be zero.
The given question is incomplete. The complete question is:
A chemist prepares a solution of barium chloride by measuring out 110 g of barium chloride into a 440 ml volumetric flask and filling the flask to the mark with water. Calculate the concentration in mole per liter of the chemist's barium chloride solution. Round your answer to 3 significant digits.
Answer: Concentration of the chemist's barium chloride solution is 1.20 mol/L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L
moles of 
(solute) = 
Now put all the given values in the formula of molality, we get
Therefore, the molarity of solution is 1.20 mol/L
Answer:
Dominant traits are always expressed when the connected allele is dominant, even if only one copy exists. Recessive traits are expressed only if both the connected alleles are recessive.
Explanation:
Freckles, cleft chin and dimples are all examples of a dominant trait.
