Answer:
4050 mL
Explanation:
Given data:
Mass of glucose = 150.1 g
Molarity of solution = 0.205 M
Volume of solution = ?
Solution:
Molarity = number of moles of solute / L of solution.
Now we will calculate the moles of sugar first.
Number of moles = mass/ molar mass
Number of moles = 150.1 g/ 180.156 g/mol
Number of moles = 0.83 mol
Now we will determine the volume:
Molarity = number of moles of solute / L of solution.
0.205 M = 0.83 mol / L of solution.
L of solution = 0.83 mol / 0.205 M
L of solution = 4.05 L
L to mL conversion:
4.05 L × 1000 mL / 1 L = 4050 mL

Examples of Gases
A gas does not have a defined shape or volume, so it can expand to fill any size or shape of a container. Particles in gases are widely separated, compared to those in liquids and solids.
Explanation:
The correct answer is option B. Dirty water is a mixture of solid particles and liquid. It is both a mixture and pure substance.
The dirty water sample has both gravel and liquid water in it. After filtration the gravel is removed so the water sample looks clearer than before filtration. Liquid water is a pure substance because it is a compound that is made up of elements hydrogen and oxygen. Now the gravel is only physically combined with the liquid water, thus giving the water sample properties of a mixture. And like any mixture, gravel is physically separated through filtration from the liquid water.
Thus the water sample of the chemists is both a mixture and pure substance.
