A sample of methane gas at 299 k and 0.956 atm occupies a volume of 4.65 L. If the gas is allowed to expand to a larger volume. while at the same time it is heated to a higher temperature, the final gas pressure Owill be lower than 0.956 atm. will be higher than 0.956 atm. could be higher or lower than 0.956 atm depending on the final volume and temperature.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
