According to the concept of Avogadro's number and STP conditions volume in liters of the sample is 15,388.7.

Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.

According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.

Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number

Number of moles is obtained as, number of atoms/Avogadro's number=4.088×10²⁴/6.023×10²³=6.78 moles on substitution in formula of PV=nRT=V=6.78×8.314×273/1=15,388.7 liters.

The student collected data on the mass of each artificial cell. The student predicted that the cell in the beaker with 25% sugar solution would have the greatest change in mass after 24 hours. The student's prediction would be correct.

The artificial cell placed in the beaker with 25% sugar solution would likely have the greatest change in mass after 24 hours because of osmosis.

Osmosis is the movement of water across a semi-permeable membrane from an area of high water concentration to an area of low water concentration. In this case, the artificial cell has a semi-permeable membrane that allows water to pass through, but not sugar.

The 25% sugar solution in the beaker is less concentrated than the sugar solution inside the artificial cell, so water will move from the beaker into the cell, causing the cell to swell and increase in mass.

On the other hand, the artificial cells in the beakers with 0% and 12.5% sugar solutions will have less of a change in mass as the solution outside of the cell is more concentrated than inside the cell.

The vapor pressure of water at its boiling point 100°C is 1 atm. Then the pressure at 117°C is 1.17 atm and the temperature of water at a pressure of 2.85 atm is 285°C.

Boiling point of a substance is the temperature at which it converts from liquid state to vapor state. At this temperature the vapor pressure of water vapor is equal to the atmospheric pressure that is 1 atm .

The temperature-pressure relation is written as:

P1 /T1 = P2/ T2

Now, the pressure inside the cooker at a temperature of 117°C is calculated as:

(1 atm × 117 °C) / 100 °C = 1.17 atm.

Thus, pressure at 117 °C is 1.17 atm. Then, If the pressure is 2.85 atm, then the temperature of water inside the pressure cooker is calculated as:
