Solution Chemistry Flashcards
What is concentration?
How much solute is in a solvent (ratio of solute to solvent)
Percent by Mass
What is percent by mass(%m/m)?
g solute in 100g solution.
Percent by Mass
What is the formula to percent by mass (%m/m)?
%by mass solute=
mass of solute(g)
÷ x100%
mass of solution(g)
Percent by Volume
What is percent by volume (%v/v)?
Liquid in liquid.
Percent by Volume
What is the formula for (%v/v)?
%by volume of solute=
volume of solute(ml)
÷ x100%
volume of solution(ml)
What is percent mass by volume(%m/v)?
Usually #g of solute per 100mL solution.
What is the formula for (%m/v)?
%mass/volume=
mass of solute(g)
÷ x100%
volume of solution(g)
What is the use of parts per million(ppm)?
For small quantities.
What is the formula for parts per million (ppm)?
ppm=
mass of solute(g)
÷ x10^6
mass of solution(g)
What is the use of parts per billion(ppb)?
For smaller quantities
What is the formula to parts per billion(ppb)?
ppb=
mass of solute(g)
÷ x10^9
mass of solution(g)
cows milk contains 4.0 g of lactose per 100m of milk. what mass of lactose is present in one 250ml of milk
11.3g
a 10% M/V salt solution is used fr making pickles. what mass of salt is present in 750ml of this solution
g=75g
to make a hand cleaner, a technician mixes 30ml of antiseptic with enough liquid soap to make 70ml of solution. determine the present by volume concentration of the antiseptic in the hand cleaner.
43% V/V
a solution of rubbing alcohol is labelled 60.0%(v/v). determine the volume of rubbing alcohol present in a 200ml sample of solution
120ml
a bottle of insect repellent states that it has a DEFT. present by volume concentration of 25%. if you just bought a 250ml container of this product, what volume of DEFT have you purchased
62.5ml
what is the formula to percent by volume
% volume of solute=volume of solute (ml) / volume of solute(ml) x 100%
