Aflask that weighs 345.8 g is filled with 225 ml of carbon tetrachloride.
the weight of the flask and carbon tetrachloride is found to be 703.55 g.
from this information, calculate the density of carbon tetrachloride.

The density of carbon tetrachloride is 1.59 g/cm^3.

Given the following data:

To find the density of carbon tetrachloride;

First of all, we would determine the mass of carbon tetrachloride;

Mass of flask and carbon = mass of flask + mass of carbon tetrachloride

703.55 = 345.8 + mass of carbon tetrachloride

Mass of carbon tetrachloride = 703.55 - 345.8

Mass of carbon tetrachloride = 357.75 g

Next, we would solve for the density of carbon tetrachloride by using the formula;

Substituting the values into the formula, we have;

Density = 1.59 g/cm^3

Therefore, the density of carbon tetrachloride is 1.59 g/cm^3.

1.59 g/mL

Explanation:

Mass of CCl₄ = mass of flask and CCl₄ − mass of empty flask

m = 703.55 g − 345.8 g

m = 357.75 g

Density = mass / volume

d = 357.75 g / 225 mL

d = 1.59 g/mL

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

this is a good question! i'll do some research and come back when i have the answer!
