text: An easier way is to approximately calculate the density rather than trying to measure it.\n\nAbbrivations used:\ncc = cubic centimeter\nmL = milli-liter\ng = gram\n\nYou used one cup of water and a tablespoon of the additive.\n\n1 U.S. tablespoon = 0.5 U.S. fl. oz. (14.8 mL, 14.8 cc)\n1 U.S. cup = 8.0 fl oz (U.S. fluid ounces) (237 mL, 237 cc)\n\nWater density = 1.000 g/cc, liquid\n[from: http://en.wikipedia.org/wiki/Water]\n\nVegetable Oil Calculation:\nLiquid Vegetable Oil density = 0.93 g/cc\n[from: http://www.mcelwee.net/html/densities_of_various_materials.html]\n\nTo get the combined density of oil and water, multiply each volume by the density of each substance and divided by the total volume:\n\nDensity:\n((0.93 g/cc * 14.8 cc) + (1.000 g/cc * 237 cc)) / (14.8 + 237 cc)\n=  (13.764 g + 237 g) / 251.8 cc\n= 0.995 g/cc [for vegetable oil and water]\n\nSalt & Water Calculation:\nNaCl (table salt) density = 2.16 g/cc, solid\n[from: http://en.wikipedia.org/wiki/Nacl]\n\nYou added 14.8 mL of salt to the water (237 mL) for a total volume of 251.8 mL (251.8 cc)\n\nTo get the combined density of salt and water, multiply each volume by the density of each substance and divided by the total volume:\n\nDensity:\n= ((2.16 g/cc * 14.8 cc)  + (1.000 g/cc * 237 cc)) / 251.8 cc\n= (31.968 g + 237 g) / 251.8 cc\n= 1.068 g/cc [for salt and water together]\n\nSugar and Water Calculation:\nSugar (sucrose) density = 1.587 g/cc, solid\n[From: http://en.wikipedia.org/wiki/Sucrose]\n\nYou added 14.8 mL of sugar to the water (237 mL) for a total volume of 251.8 mL (251.8 cc)\n\nTo get the combined density of sugar and water, multiply each volume by the density of each substance and divided by the total volume:\n\nDensity:\n= ((1.587 g/cc * 14.8 cc)  + (1.000 g/cc * 237 cc)) / 251.8 cc\n= (23.488 g + 237 g) / 251.8 cc\n= ( 260.488 g) / 251.8 cc\n=  1.0345 g/cc [for sugar and water together]\n\nHope this helps!
