quiz 11

Question 1

calculate the molarity

Answer 1

mol of solute/ volume of solution (if in grams covert to mol) USE L FOR VOLUME

Question 2

calculating mass with molarity

Answer 2

multiply mol * volume, then convert mol to grams

Question 3

finding molality

Answer 3

m= moles solute/ mass solvent
convert mass to mol then divide (kg)

Question 4

mole fraction formulas

Answer 4

mol solute/ mol solvent
/ mol solution

Question 5

finding the mole fraction for solute or solvent

Answer 5

convert mass into mol for both the solute and the solvent.
add the two sums = mol solution
sum of what’s being found/mol solution

Question 6

calculating molarity with dilution

Answer 6

MsVs=MnVn
molarity= Mn

Question 7

Answer 7

subtracting Vn by Vs

Question 8

vH20 added =

Answer 8

Vn

Question 9

calculating concentration

Answer 9

“diluted with” = vH20
finding Ms

Question 10

how does gas change with pressure and temp

Answer 10

decreases as temp increases
increases as pressure increases
