The stronger intermolecular force has been found in glycerol with high viscosity as it has a larger molar mass. Thus, option A is correct.
The viscosity has been defined as the resistance of the fluid to the deformation. The viscosity has been dependent on the molar mass and intermolecular force in the compounds.
The stronger intermolecular force and molar mass tend to have more resistance to the deformation and thus have more viscosity.
The intermolecular force present in glycerol and water is hydrogen bonding. The molar mass of glycerol has been higher than water, this tends to have more resistance and viscosity.
Thus, glycerol has high viscosity as it has a larger molar mass. Thus, option A is correct.

Melt chocolate and measure the temperature and then melt wax and measure the temperature and compare his results.
To find net force, you simply add all of the forces together.
Answer: 670N
To
determine the volume of both concentration of the solution to make another concentration of solution, we need to set up
two equations since we have two unknowns. <span>
For the first equation, we do a mass balance:
mass of 50% solution + mass of 20% solution =
mass of 40% solution
M1 + M2 = M3
For the second equation, we do a component balance,</span>
<span>
M1(50%) + M2(20%) = M3(40%)
.50M1 + .20M2 = .40M3
To determine the ratio, we assume we have to make a 100 g of the 40% solution. So, the equation would change to</span>
<span>
</span>
<span>M1 + M2 = 100</span>
.50M1 + .20M2 = (100)(.40) = 40
Solving for M1 and M2,
M1 = 66.67 g
M2 = 33.33 g
So, the ratio of the 20% and the 50% would be approximately 33.33/66.67 = 0.5.
