An object with a mass of 421 g is added to 50.0 mL of water. The water level rises to a volume of 76.0 mL. What is the density of the object
a nugget of gold with a mass of 281 g is added to 50.0 ml of water. the water level rises to a volume of 77.0ml what is the density of the gold
When 25 g of the unknown metal were added, the water was displaced 3.50 mL. Calculate the density of the unknown metal. Remember, density = mass/volume. Express your answer as g/cm3 ( 1 mL = 1 cm3). Choose the closest answer. How many significant figures should be shown in the final answer?
In the lab, a student fills a dry 50 mL graduated cylinder with 30.0 mL of water. The mass of the water in the graduated cylinder was 30.743 grams at 25°C. What is the true volume of the water measured in the graduated cylinder? The density of water at 25°C is 0.99707 g/mL.
Answer the following solution concentration questions How much water must be added to 40.0 g of CaCl, to produce a solution thatis 35.0% CaCl2? a. b. You can purchase hydrochloric acid in a concentrated form that is 36.0 % HCl by mass and that has a density of 1.20 g/mL. Describe exactly how to prepare 1.15 L of 0.500 M HCI from the concentrated solution
A solid has a mass of 21.15 grams and a density of 1.688 g/mL. The solid is dropped into a graduated cylinder containing water with volume of 15.00 mL. When the solid is dropped into the graduated cylinder, the volume of the water goes up. Using the information given, calculate the final volume of the water in the graduated cylinder.
