Answer:
Molarity = 0.5 M
Osmolarity = 0.5 x 2 = 1 Osmpl.
Molecules of Cl2 = 6.02 x 
/ 4= 1.505 x no. of molecules
Explanation:
If we add half mole in 1L volume than molarity will obviously be 0.5 M.
The osmolarity is molarity multiplies by number of dissociates of solute that for CaCl2 are 2. So, 2 x 0.5 = 1
Half will be molecules of Ca and half will be of Cl2 for 0.5M.
The volume of the flask would simply be equal to the
volume of the water. And the mass of the water would be the difference after
and before weigh.
mass of water = 489.1 g – 241.3 g
mass of water = 247.8 g
Therefore the volume of water (which is also the volume
of the flask) is:
volume = 247.8 g / (1.00 g/cm^3)
volume = 247.8 cm^3
The total mass of the flash when filled with chloroform
would be:
total mass with chloroform = 241.3 g + 247.8 cm^3 (1.48
g/cm3)
total mass with chloroform = 608.04 g
Answers:
volume = 247.8 cm^3
total mass with chloroform = 608.04 g
Multiple states of matter - mixture
Same state of matter - pure
Separated physically- mixture
Consistent properties - pure
Can’t be separated- pure
Can’t be a single element - mixture
