In an experiment, you combine water (density = 1.00 g/mL) and hexane (density = 0.66 g/mL) in a beaker to make a mixture with a total volume of 354.4 mL and a total mass of 312.9 g. Water and hexane do not mix. What is the volume of water in the mixture?

A student performs an experiment to determine the density of a sugar solution. She obtains the following results: 1.70 g/mL, 1.75 g/mL, 1.66 g/mL, and 1.68 g/mL. How should she report the average density of her measurements, including the uncertainty?

Calculate the temperature in °C of nitrogen gas (N2) with a density of 2.28 kg/m³ at a pressure of 2 atm. (Assume ideal gas behavior and use R = 0.0821 L·atm/mol·K for calculations.)

Calculate the number of atoms in a copper rod with a length of 9.85 cm and a radius of 1.05 cm. The density of copper is 8.96 g/cm³. (The volume of a cylinder is V = πr²l.) Express the number of atoms to three significant figures. Assume the molar mass of copper is 63.55 g/mol and Avogadro's number is 6.022 × 10²³ atoms/mol.

Greg has a blood volume of 5.9 qt. If the density of blood is 1.06 g/mL, what is the mass, in grams, of Greg's blood? (Note: 1 qt = 946.353 mL)

Pb has a density of 11.3 g/cm³. What is the mass of a cube of lead with a length of one side equal to 50.0 mm?

The density of a sample of wine is 1.08 g/mL. If a Salmanazar of wine is 9.00 liters, what is the weight of 3.67 Salmanazars of wine in ounces?

What is the density (in g/mL) of a 1.0 kg mass in 1500.0 mL?

What is the density (in kg/L) of a material that has a mass of 430.0 g in 0.125 L?
