I Hope this is right if not so sorry :)
Plasma's that reach a temperature equal to their surroundings
someone already asked this question by the way you should search it next time so you don't waste any points : )
From the calculations and by the use of Boyles law, the new pressure of the gas is 1.7 atm
<h3>What are gas laws?</h3>
The term gas law is used to demonstrate the relationship between the volume, pressure, number of moles and temperature of a gas.
Using the Boyles law;
P1 = 1 atm
P2 = ?
V1 = 6 L
V2 = 3.5 L
P1V1= P2V2
P2= P1V1/V2
P2= 1 atm * 6 L/3.5 L
= 1.7 atm

B.) Weight.
Weight is the combination of gravity on mass, thus it produces a force. (gravity is the force)
Answer:
Π = 21.9 atm
Explanation:
The equation used to find osmotic pressure is:
Π = iMRT
In this formula,
>> Π = osmotic pressure (atm)
>> i = van't Hoff factor
>> M = molarity (M)
>> R = constant (0.0821 atm*L/mol*K)
>> T = temperature (K)
Remember, van't Hoff factor is the amount of ions the species (MgCl₂) dissociates into while in solution. MgCl₂ dissociates into 3 ions. These ions are Mg²⁺ and 2 Cl⁻.
The temperature needs to be in Kelvin....
37.0 °C + 273.15 = 310.15 K
You now know the value of all the variables.
Π = iMRT
Π = (3)(0.287 M)(0.0821 atm*L/mol*K)(310.15 K)
Π = 21.9 atm
