Answer:
The density of this liquid is 0.320 kg/L
Explanation:
Given:
Volume of the Liquid = 0.820 L
Mass of the liquid = 2.56 kg.
To Find:
The density of the liquid in kg/L
Solution:
Density is the mass occupied by the substance in unit volume. This density is essential determining whether the substance floats or sinks. Greek letter(rho) is used to denote density
The equation of for density is
where m is the mass
v is the volume
On substituting the given values
Taking into account the Boyle's law, 3.377 L of helium the tank will be able to produce at a pressure of 94.2 kPa.
The gas laws are a set of chemical and physical laws that allow determining the behavior of gases in a closed system. The parameters evaluated in these laws are pressure, volume, temperature, and moles.
Boyle's law is one of the gas laws that relates the volume and pressure of a certain quantity of gas kept at constant temperature.
This law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. That is, if the pressure increases, the volume decreases; while if the pressure decreases, the volume increases.
Mathematically, Boyle's law states that the product of pressure and volume is constant:
P×V= k
Studying two different states, an initial state 1 and a final state 2, it is satisfied:
P1× V1= P2×V2
In this case, you know:
Replacing in Boyle's law:
101 kPa× 3.15 L= 94.2 kPa× V2
Solving:
<u><em>V2= 3.377 L</em></u>
In summary, 3.377 L of helium the tank will be able to produce at a pressure of 94.2 kPa.
