Rubbing alcohol is 70.% (m/v) isopropyl alcohol by volume. how many ml of isopropyl alcohol are in a 1 pint (473 ml) container?
g100num [7]
 The number  of ml of isopropyl  alcohol  that are 1 pint (473 Ml)   is  331.1 Ml

   calculation
 
assume  that  the 1 pint  is in  a  container

  
This implies  that the 1 pint (473 ml)  is  in 100 %  M/V
      what about 70 %(M/V)

 that is  473 Ml  = 100 %
                   ?   =   70 %

by  cross  multiplication
    =  473 x70/100 = 331.1 Ml

In this experiment you used an excess of the BaCl2 solution. How would your results be affected if you did not use an excess of
Igoryamba

if we did not use an excess of the BaCl2 solution it would decrease the mass percentage of sulfate in the unknown sample.

The net precipitation equation would be.

Ba2+(aq) + SO42-(aq)  → BaSO4(s)

If BaCl2 (Ba2+) is not taken in excess then the precipitation would not be completed as some of the sulfate ions would still be remaining in the solution. This would decrease the mass percentage of sulfate in the unknown sample.

If some tiny pieces of filter paper still remained mixed with the precipitate(BaSO4) then the mass of sulfate would increase and it gives a high mass percentage of the sulfate.

mass percentage of sulfate = (mass of sulfate/mass of sample)*100
