C) esophagus - moves air from the nose into the lungs

Explanation:

The oesophagus is a muscular tube with a sphincter valve at each end. Its main function is to transport food and fluid, after being swallowed, from the mouth to the stomach.This is propelled from the pharynx into the oesophagus, and towards the stomach in a peristaltic waves. The peristalsis also pushes food along the alimentary canal

How many grams of urea (non volatile, non electrolyte) must be added to 1250. g water to give a solution with a vapor pressure l
Lady bird [3.3K]

Answer:

\large\boxed{\large\boxed{107g}}

Explanation:

The <em>vapor pressure lowering</em> is a colligative property and it follows  Raoult's law.

The <em>vapor pressure lowering</em> of a solvent in a solution, ΔP, is equal to the mole fraction of the solute, Xsolute, multiplied by the vapor pressure of the pure solvent, P°.

               \Delta P=X_{solute}\times P^0

ΔP and P⁰ are given:

  • ΔP = 1.39mmHg
  • P⁰ = 55.32mmHg

<u>1. Mole fraction of solute</u>

Thus, you can calculate Xsolute:

           1.39mmHg=X_{solute}\times 55.32mmHg\\\\X_{solute}=0.02513

<u>2. Moles of solute</u>

Now you can calculate the number of moles of water and the number of moles of solute.

  • Number of moles of water = mass in grams / molar mass

  • Number of moles of water = 1,250g/18.015 (g/mol) = 69.3866mol

  • Xsolvent = 1 - Xsolute = 1 - 0.02513 = 0.97487

  • Xsolvent = moles of solvent / moles of solution

  • 0.97487 = 69.3866mol / moles of solution

  • moles of solution = 71.1752mol

  • moles of solute = moles of solution - moles of solvent = 71.1752mol - 69.3866mol = 1.7886mol

<u>3. Mass of urea</u>

Formula:

  • Mass = number of moles × molar mass
  • Mass = 1.7886 mol × 60.06 g/mol = 107.42 g

You must round to 3 significant figures: 107 g
