The mass of the sample is reported as 25 g, and it is weighed on a balance with a precision of 0.001 g.
Since the mass is expressed as "25 g," this indicates that the measurement is precise to the nearest gram, and it contains two significant figures (the digits '2' and '5'). The precision of the balance does not change the number of significant figures in the mass reported unless the mass itself is provided with a decimal point that indicates additional precision.
Therefore, the number of significant figures in the reported measurement of the mass is **2**.
