The intracellular fluid (ICF) compartment is the system that includes all fluid enclosed in cells by their plasma membranes. Extracellular fluid (ECF) surrounds all cells in the body. Extracellular fluid has two primary constituents: the fluid component of the blood (called plasma) and the interstitial fluid (IF) that surrounds all cells not in the blood.
Answer:
1.574
Explanation:
Given that:
Gram of solution = 100 g
Solution = solute + solvent
Solute = 6.75% = (6.75 / 100) * 100 = 6.75 g (Ethanol) (C2H5OH)
Solvent = 100 - 6.75 = 93.25 g
Recall :
Molality = (mol of solute / kg of solvent)
Mole of solute = gram / molar mass
Molar mass of C2H5OH = (12 * 2) + (1 * 5) + 16 + 1 = 46g/mol
Mole = 6.75g / 46g/mol
Mole = 0.1467391
93.25 g to kg
1000 g = 1 kg
93.25 g = 93.25 / 1000 = 0.09325
Hence,
Molality = 0.1467391 / 0.09325
= 1.5736096
= 1.574
Answer:
Since boron only has two electron shells, it is about as capable of gaining electrons as it is of losing electrons, so it behaves as a metalloid. The other elements in this group have more electron shells, so it is much easier for them to lose their valence electrons and they behave like metals.
