Question 1113854: You need 100mL of alcohol to conduct an experiment buy you only have unmarked beaker(you do not have a graduated cylinder). You know that alcohol (ethanol) has a density of 0.785 g/mL. How can you obtain the correct volume of alcohol using only a mass balance and an empty container? What is the total mass of the unmarked beaker and 100mL of alcohol if the beaker has mass of 70g when empty?

Amount of MASS of alcohol to use:
100%2AmL%2A%280.785%29%28g%2F%28mL%29%29=highlight%2878.5%2Agrams%29-------mass of the alcohol


If the beaker to use is already 70 grams, then the needed alcohol AND the beaker would be 148.5 grams.
