Using the given information, construct a calibration curve and determine the exact concentration of a sugar- water solution with a density of 1.25 g/m Concentration 60% 40% 20% 10% Volume (mL) 25.2 25.1 25.0 25.1 Mass of Solution (g) 32.28 29.74 27.01 26.53 Print Layout View Sec 1 Pages: 101 3 Words: 001338 144% WOA

Explanation / Answer

density = mass/ volume, the data on mass and volume is converted to density from the formula of density.

the density of the given solutions are calculated

density (g/ml) and concentration in wt% is created. the plot is shown below.

the equation of best fit is density= 0.003* wt%+1.017

when density is 1.25

the equation becomes 1.25= 0.003*wt% +1.017

wt%= (1.25-1.017)/0.003=77.77%
