photoshop1234 [79]

Answer:

intracellular; extracellular

Explanation:

Intracellular fluid compartment is system which includes all the fluid which is enclosed in the cells by the plasma membranes of these cells. It lies in the cells and acts as the principal component of cytoplasm. ICF makes up about 2/3 of total water in human body.

Extracellular fluid is system which surrounds all the cells in body. The fluid has two primary constituents which are - fluid component of blood (known as plasma) and interstitial fluid (IF) which surrounds all the cells except blood. It accounts for other 1/3 of water content of the body.

I will give brainliest!!! What is the density of a sample of chlorine gas that exerts a pressure of 4.5 atm in a 12.6 L containe
labwork [276]

Answer : The density of a sample of chlorine gas is, 12.59 g/L

Explanation :

To calculate the density of chlorine gas we are using ideal gas equation.

PV=nRT\\\\PV=\frac{w}{M}RT\\\\P=\frac{w}{V}\frac{RT}{M}\\\\P=\frac{\rho RT}{M}

where,

P = pressure of chlorine gas = 4.5 atm

V = volume of chlorine gas = 12.6 L

n = number of moles of chlorine gas

w = mass of chlorine gas

R = gas constant = 0.0821 L.atm/mol.K

T = temperature of chlorine gas = 36^oC=273+36=309K

M = molar mass of chlorine gas = 71 g/mol

Now put all the given values in the above formula, we get:

P=\frac{\rho RT}{M}

4.5atm=\frac{\rho \times (0.0821L.atm/mol.K)\times (309K)}{71g/mol}

\rho=12.59g/L

Therefore, the density of a sample of chlorine gas is, 12.59 g/L
