The ideal gas law predicts gas behavior including the relationships between the number of moles, volume, pressure, and temperature. Predict the changes in volume of a helium-filled balloon at different temperatures. When you took the balloon outside on a cold day, the helium atoms inside move slower and its volume decreased because the atoms didn't exert as much pressure on the balloon walls. Calculate the volume in L of a balloon filled with 0.250 moles of helium at 1.00 atm at 0.00°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.
