A mole is mean the atomic number of 12 grams of carbon 12.
Answer:
The human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape.
Molality of solution = 0.529 m
mass solvent in kg = 20.6 g => 20.6 / 1000 => 0.0206 kg
number of moles = molality x mass solvent
= 0.529 x 0.0206 => <span> 0.0108 mol benzene
</span>
hope this helps!
