Answer is 30.0mL
according to the question dilution is performed by the student which can be calculated with the help of :
EQUATION (1)
Here, we have:
= 3M
= y mL
= 1.80 M
= 50.0mL
putting the known values in equation (1) which will give us value of 
3.00× y =1.80 ×50.0
y= 30.0mL
The solution in which the solute particles are suspended in a liquid (fluid) is called colloidal solution. Colloid is a solution that has particles ranging between 1 and 1000 nanometres. Cheese is a solid emulsion in which liquid is solute and solid is solvent. Hence, cheese is colloidal solution of liquid in solid.
