What is the mass percent of 60 g NaCl in a 200-g solution? Express your percent as a decimal.

What is the Mass of solvent in grams? Add together the masses of the liquid water and ice added to the calorimeter. Convert the volume of liquid water to mass using 1.000 g/mL as the density of water (see procedure for volume used). Side note:Molarity of the solution is  0.76612903225806

Data obtained: Chips # of extractions Chips' weight (g) Fat weight (g) Regular  3 20.043 6.745   3 20.187 6.438   3 20.198 7.451 Low fat  3 19.456 3.982   3 20.072 4.547   3 20.192 4.589   Mass percent is a method of expressing the concentration of a substance in a mixture or element in a compound. It is calculated as the mass of the component divided by the total mass of the mixture and then multiplied by 100 to get the percent. The formula is: mass % of component= (mass of component / total mass) x 100%   1) Reproduce the following table, and use the data to determine the mass % of fat in the chips for each trial. 2) Show one example calculation. Chips Trial % by mass of fat Regular 1     2     3   Lowfat 1     2     3
