In practice, chemists rarely try to measure out a specific mass. Instead, they estimate the mass required and spoon out the mass approximately. Then they measure the mass of the sample precisely and convert it into an amount in moles to find the precise amount that they have obtained. Why do chemists typically not want to measure out very precise, predetermined masses when making up solutions?
