When asked to graph a sucrose solution concentration (w/v%) and a Sucrose Solution Density (g/ml), does the line have to go through the origin because of the density or can it be anywhere else on the graph?

Q12. Determine the mass (in g) of each sucrose solution that contains 19 g of sucrose. part A 4.5 % sucrose by mass part B 2.7 % sucrose by mass part C 13.3 % sucrose by mass Q.13 The percent concentration of a solution is a ratio of the amounts of dissolved solute and solution, expressed as a percentage. The percent concentration of a solution can be written generally as %concentration=amountofsoluteamountofsolution×100% A mass percent concentration may be calculated for mass/mass...
