Answer:
dsf
Explanation:
It is known that density is the amount of mass present in per liter of a substance.
Mathematically, Density =
It is given that mass is 2.75 kg or 2750 g (as 1 kg = 1000 g) and volume is 250 .
Therefore, calculate the density of substance as follows.
Density =
=
= 11
Thus, we can conclude that density of given substance is 11

Explanation:
Given parameters:
Initial volume = 547L
Initial temperature = 331K
Final temperature = 376K
Unknown:
Final volume = ?
Solution:
The appropriate gas law to use is the Charles's law.
The Charles's law shows the relationship between the volume and temperature of a gas under constant pressure.
The law states that "The volume of a fixed of a gas varies directly as its absolute temperature if the pressure is constant".
Mathematically;
V₁ is the initial volume
T₁ is the initial temperature
V₂ is the final volume
T₂ is the final temperature
Since the unknown is the final volume, we make it the subject of the expression;
V₂ =
V₂ = 621.4L
