Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

The density of your soda mixture after removing all carbon dioxide was found to be 0.91 g / m * L The total mass of your soda mixture was measured to be 265.565 g. What is the volume in liters of the soda mixture? Report your answer to two decimal places.
An empty beaker weighs 38.315 g. A 5.00 mL pipet sample of an unknown liquid was transferred to the beaker. The beaker weighs 44.953 g when weighed with the liquid in it. Calculate the density of the unknown liquid. Report a numerical value only in unit of grams per milliliter.
A sample of unknown liquid is poured into a graduated cylinder and the volume of the unknown is 23.5 mL. The liquid used to fill the cylinder weighs 98.4g. From this information, calculate the density of this unknown liquid.
A sample of gold alloy has a mass of 9.3 kg. It is determined that 0.6 kg of the alloy is actually made up of copper and zinc, with the remainder being gold. Calculate the percentage of this gold in the alloy? Express your answer to the nearest percentage (nearest ones place). Hint: calculate the mass in grams of the gold in the alloy, divide by the whole mass of the alloy, and multiply by 100%. Round your answer to two significant figures. (I had to alter the wording of this question since it wasn't calculating significant figures properly, so if you got it wrong because of significant figures you can assume you probably actually got it correct.)
The weight of a metal sphere was measured to be 9.81 g. Unfortunately, the caliper that was supposed to be used in measuring the dimensions of the sphere broke. The metal that make up the sphere was identified to be an alloy of iron and chromium with a density of 7.26 g/cm3. Using the data given, calculate the radius of the metal sphere in cm. Round your answer to 2 decimal places.
