(a)
Interpretation:
Whether a balloon filled with the given gas would rise in the air or drop to the ground is to be stated.
Concept introduction:
Density is the ratio of mass to its volume. For solid bodies densities are usually expressed in the units of grams per cubic centimeter, for liquids in the units of grams per milliliter and for gases in units of grams per liter.

- In the following scenario, identify which of the statements represents a theory, law, or hypothesis. (a) A student exploring the properties of gases proposes that is she decreases the volume of a sample of gas then the pressure exerted by the sample will increase (b) Many scientists over time have conducted similar experiments and have concluded that pressure and volume are inversely proportional. (c) She proposes that the reason this occurs is that if the volume is decreased, more molecules will collide with a given area of the container walls, causing the pressure to be greater.arrow_forward60. When tin comes in contact with the oxygen in the air, tin(IV) oxide, SnO2, is formed. Sn(s) + O2(g) SNO2(s) A piece of tin foil, 8.25 cm × 21.5 cm × 0.600 mm (d = 7.28 g/cm³), is exposed to oxygen. (a) Assuming that all the tin has reacted, what is the mass of the oxidized tin foil? (b) Air is about 21% oxygen by volume (d = 1.309 g/L at 25°C, 1 atm). How many liters of air are required to completely react with the tin foil? |Darrow_forwardA sample of nitrogen gas, N2, travels 17.0 cm in 4.5 minutes.

- The mass of an iron nail is measured before and after being placed in a beaker of water for 2 days. It is found that 0.059 g of iron (3) oxide (rust) was produced over the 2-day period. What mass of iron in the nail reacted with the water? Assume the nail is pure ironarrow_forwardTwo identical balloons are filled to the same volume, one with air and one with helium. The next day, the volume of the air-filled balloon has decreased by 4.5 %. By what percent has the volume of the helium-filled balloon decreased? (Assume that the air is four-fifths nitrogen and one-fifth oxygen, and that the temperature did not change.) Express your answer using two significant figures.arrow_forward(a) A sample of tetrachloroethylene, a liquid used in dry cleaningthat is being phased out because of its potential to cause cancer,has a mass of 40.55 g and a volume of 25.0 mL at 25 °C. Whatis its density at this temperature? Will tetrachloroethylene floaton water? (Materials that are less dense than water will float.)(b) Carbon dioxide (CO2) is a gas at room temperature andpressure. However, carbon dioxide can be put under pressure tobecome a “supercritical fluid” that is a much safer dry-cleaningagent than tetrachloroethylene. At a certain pressure, the densityof supercritical CO2 is 0.469 g/cm3. What is the mass of a25.0-mL sample of supercritical CO2 at this pressure?arrow_forward

If you know that each copper atom (radius = 128 pm) has a mass of 1.055 ×10–22 g (you will learn in Chapter 2 how to find the mass of one atom), how manyatoms are there in this cube? What fraction of the cube is filled with atoms? (Orconversely, how much of the lattice is empty space?) Why is there “empty” space in thelattice?(b) Now look at the smallest, repeating unit of the crystal lattice of copper.Knowing that an edge of this cube is 361.47 pm and the density of copper is 8.960g/cm3, calculate the number of copper atoms in this smallest, repeating unitarrow_forwardthe us national institute of standards and technology used mercury gauge as a primary standard for pressure until is was decommissioned in 2019. the device was 3.00 meters tall and contained 225 kilograms of mercury. if the density of mercury is 13.6 g/ml, what was the volume of mercury contained in this device in liters?arrow_forward
