Answer : The density of the object will be,
Explanation :
Density : It is defined as the mass contained per unit volume.
Formula used for density :
Given :
Mass of an object = 5.0 grams
Volume =
Now put all the given values in the above formula, we get the density of an object.
Therefore, the density of the object will be,
The totalpressure in the container is 1.03 atm, which is the sum of the pressure of the carbon dioxide (1 atm) and the partial pressure of the water vapor (0.03 atm) at 25.0°C.
The question is asking about the total pressure in a container after the sublimation of carbon dioxide at a certain temperature in the presence of water. Carbon dioxide sublimates (turns from solid directly to a gas) at normal atmospheric pressure, which is 1 atm. Sublimation is a phase transition in which a solid turns into a gas without passing through the liquid phase. In this case, the CO2 sublimates and is collected in a container over water.
However, as the gas is collected over water, it also becomes saturated with water vapor. The total pressure in the container is therefore the sum of the partial pressure of the carbon dioxide plus the partial pressure of the water vapor. At 25.0°C, the partial pressure of the water vapor is about 0.03 atm. Therefore, the total pressure in the container will be 1 atm (from the CO2) + 0.03 atm (from the water vapor) = 1.03 atm. This is the total pressure in the container.

The total pressure in the container is 1.03 atmospheres, combining the pressure of sublimated CO2 (1.00 atm) and the vapor pressure of water at 25.0 °C (0.03 atm).
To determine the total pressure in the container containing carbon dioxide and water vapor, we need to consider both the dry gas pressure and the vapor pressure of water. Carbon dioxide sublimes at 1.00 atm at standard atmospheric pressure. However, the gas collected over water becomes saturated with water vapor. The pressure of the pure CO2 gas is therefore equal to the total pressure minus the vapor pressure of the water. The vapor pressure of water at 25.0 °C is approximately 0.03 atm. Therefore, the total pressure in the container is the sum of the pressure due to the carbon dioxide and the water vapor, which equals 1.00 atm + 0.03 atm = 1.03 atm.

B. The number of electrons ranges from 1 to 3.
C. The number of neutrons ranges from 0 to 2.
D. The number of protons ranges from 0 to 2.
The correct answer is C.
A substance is said to exhibit isotopy if the number of proton and neutron in the nucleus of the atom differs, whille the number of proton and electron are the same. Hydrogen has three isotopes and each of the isotopes has different number of neutron. Hydrogen 1 has no neutron but have 1 proton, hydrogen 2 has 1 neutron and 1 proton and hydrogen 3 has 1 proton and 2 neutrons.
