If he pressure of a gas is 2.42 atm, what is it’s pressure in kpa? a) 0.00318 kpa b) 0.0239kpa c) 245 kpa d) 1,840 kpa

Pressure of a gas is the force that the gas exerts on the walls of its container. The pressure indicates the movement of gas molecules. Gas molecules move from an area of high pressure to an area of low pressure. Pressure is expressed in the units of atm, Pa, Torr, and mmHg

The given pressure of the gas = 2.42 atm

The conversion factor from atm to kPa is 1 atm=101.325 kPa

Converting the pressure from atm to kPa:

Therefore a pressure of 2.42 atm is equivalent to a pressure of 245 kPa.

Correct option: C) 245 kPa

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
