Answer:
455.4 mmHg
Explanation:
To solve this problem we can use <em>Gay Lussac's Law</em>, which describe the temperature and pressure of a gas, at constant volume and composition:
In this case:
We <u>input the data</u>:
- 621 mmHg * 231 K = P₂ * 315 K
And <u>solve for P₂</u>:
Weight of Chloroform : = 2.862 kg
<h3>Further explanation</h3>
Given
Density 1.483 g/ml
Volume = 1.93 L
Required
Weight of Chloroform
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:

ρ = density
m = mass
v = volume
Convert density to kg/L :
=1.483g/ml = 1.483 kg/L
So the weight(mass) :
= ρ x V
= 1.483 kg/L x 1.93 L
= 2.862 kg
<span>We can use rocks to determine if the animals from to day have changed from the past.
Rocks also help us know if rivers once flowed through an area.
We use them to find out what type of animals live then that are extinct now.</span>
