CHEM COLLIGATIVE PROPERTIES AND PROPERTIES OF WATER

Question 1

it means relatively small amount of solute in solvent

Answer 1

dilute

Question 2

means relatively large amount of solute in solvent

Answer 2

concentrated

Question 3

three common ways in concentration expression

Answer 3

molarity, molality, mole fraction

Question 4

refers to solution composition, it is the ratio of the mole of one component over the total moles of solution

Answer 4

mole fraction

Question 5

ratio of the number of moles of solute over the kilograms of solvent

Answer 5

molality

Question 6

the main difference between molality and molarity

Answer 6

in molarity there is a change in volume of the solution from contraction and expansion, meanwhile molality itself does not change with temperature due to its mass

Question 7

density of water

Answer 7

1 gram/milliliter

Question 8

is a concentration unit for the number of moles of solute in exactly 1 liter of solution

Answer 8

molarity

Question 9

percent concentration expressions

Answer 9

mass percent
volume percent
mass/volume percent

Question 10

describes the mass of solute in every 1g of solution

Answer 10

mass percent

Question 11

describes the volume of solute in every 100ml of solution

Answer 11

volume percent

Question 12

indicates the mass of solute in every 100ml of solution

Answer 12

mass/volume percent
