(4) C8H14 is your answer. A saturated hydrocarbon means that they have no double or triple bonds. C8H14 is an alkyne, which is an unsaturated hydrocarbon.
Answer:
0.4383 g
Explanation:
Molality is defined as the moles of the solute present in 1 kg of the solvent.
It is represented by 'm'.
Thus,
Given that:
Mass of solvent, water = 150 g = 0.15 kg ( 1 g = 0.001 g )
Molality = 0.050 m
So,
Molar mass of NaCl = 58.44 g/mol
Mass = Moles*Molar mass = = 0.4383 g
