Answer:
218 "cubic inch" = 0.05238 "rundlets"
Explanation:
From the conversion factors;
1.00 gal = 231 in3 = 3.78 L
But;
1.00 rundlet = 6.81 × 104 mL = 68.1 L (Converting to L by dividing by 1000)
231 in3 = 3.78 L
218 in3 = x
x = (218 * 3.78 ) / 231
x = 3.5673L
But 1 rudlet = 68.1 L
x rundlet = 3.5673L
x = (3.5673 * 1 ) / 68.1
x = 0.05238
The chloroplast. Chlorophyll is used for coloring, and mitochondria are energy batteries of sorts.
Answer:
motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.
Explanation:
Strong intermolecular ion-ion forces are responsible for high melting points. Thus the solid state requires close proximity and high order to have high melting point. Hope this answer helps. Good luck!
Answer:
The molar mass of the unknown compound is 202.40 g/mol.
Explanation:
Let the molar mass of compound be M.
The depression in freezing point is given by:
![\Delta T_f=K_f\times m](https://tex.z-dn.net/?f=%5CDelta%20T_f%3DK_f%5Ctimes%20m)
![\Delta T_f=T-T_f](https://tex.z-dn.net/?f=%5CDelta%20T_f%3DT-T_f)
where,
= change in boiling point = 0.81 K
=Boiling point of the solution = 3.77°C
T = freezing point of the pure solvent here benzene =5.48°C
= freezing point constant = 5.12°C/m
m = molality =![\frac{\text{Mass of solute}}{\text{Molar mass of solute}\text{Mass of solvent in kg}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BMass%20of%20solute%7D%7D%7B%5Ctext%7BMolar%20mass%20of%20solute%7D%5Ctext%7BMass%20of%20solvent%20in%20kg%7D%7D)
![\Delta T_f=5.48^oC-3.77^oC=1.71^oC](https://tex.z-dn.net/?f=%5CDelta%20T_f%3D5.48%5EoC-3.77%5EoC%3D1.71%5EoC)
![1.71^oC=5.12^oC/m\times \frac{33.8 g}{M\times 0.500 kg}](https://tex.z-dn.net/?f=1.71%5EoC%3D5.12%5EoC%2Fm%5Ctimes%20%5Cfrac%7B33.8%20g%7D%7BM%5Ctimes%200.500%20kg%7D)
M = 202.40 g/mol
The molar mass of the unknown compound is 202.40 g/mol.
