Final answer:
Sample 3 had the least mass at 0.058 g, while Sample 1 had the lowest temperature at 37.57 °C.
Step-by-step explanation:
The experiment samples provided each have a different mass and temperature. To determine which sample had the least mass, we look for the smallest numerical value in the mass column. In this case, it is sample number 3, with a mass of 0.058 g. For the lowest temperature, we examine the temperature values and see that the lowest temperature is for sample number 1, at 37.57 °C.
