John is testing the effect of temperature on the solubility of sugar in water. He plans to determine the mass of sugar dissolved in a saturated solution. He will begin with a known mass of sugar and add sugar to water until the solution is saturated. He will then calculate how much sugar dissolved by subtracting the remaining mass from the initial mass. He organized data about his experiment in the following table: Group A Group B Group C Volume of water 75 ml Temperature 250 900 5°C 1000 g Initial mass of sugar Final mass of sugar Which of the following would be the best volume of water to use in Group C? A. 25 mL B. 140 mL C. 270 mL D. 75 mL SUBTIT
