Is there a way to determine the number of moles in a sample of a substance?
Yes, there are several methods for determining the number of moles in a sample. One method is by using the ideal gas law equation PV=nRT where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature. Another method involves measuring the density of the substance and then calculating the number of moles based on the mass and volume of the sample.
