An empty beaker weighs 39.81 g. When completely filled with water, the beaker and its contents have a total mass of 292.55 g. What volume does the beaker hold? Use d = 1.00 g/mL as the density of water. volume: mL How much would the beaker and its contents weigh if it was completely filled with mercury? The density of mercury is d = 13.5 g/mL. total mass:

The volume of a gold idol is approximately 1.0L. The density of gold is 19.3 g/ml and the density of sand is 2.3 g/ml. What volume would the bag of sand be in order to weigh exactly the same as the idol?

Given the following data, calculate the percentage of salt in the original mixture.  Include the % unit and two decimal places in your answer. Mass of mixture = 4.578 g Mass of 400 mL beaker = 137.253 g Mass of 400 mL beaker and sand = 139.088 g Mass of 250 mL beaker = 105.77 g Mass of boiling chips = 0.548 g Mass of 250 mL beaker + boiling chips + salt = 108.834 g
