The temperature difference between day and night on Mars is much bigger than on Earth, due to its low atmospheric pressure. As mentioned above, the daytime temperature at the equator in summer on Mars is about 21°C. At night, it drops to about - 73°C! A syringe contains a sample of a gas with a volume of 12.0 mL during the day (21°C). What volume will the gas occupy at nighttime (- 73°C)?

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.
