1
Q
how to find the mass of the solution before evaporation
A
take mass of beaker and soda - mass of beaker= g
2
Q
calculate density
A
mass solution before evaporation/ volume of solution= g/ml
3
Q
mass solution after evaporation
A
mass of beaker + residue - mass of beaker
4
Q
% dissolved solid
A
mass evap/ mass solution before evap x 100
5
Q
% H20 + CO2
A
(mass beaker + soda)- (mass beaker + residue)/ mass sol before evap x 100
6
Q
total mass of dissolved solids in 2l
A
(g solid sugar/ 50ml) x 2L
