You perform an experiment in which you find out how much mass evaporates from a liquid when it is placed in direct sunlight or in the shade. which piece of technology is appropriate for gathering the experimental data you need? a. tape measure b. thermometer c. computer d. scale

The correct option is SCALE.
This is because the experimental data you are interested in is mass and scale is the instrument that is used to measure mass. To use the scale, measure the mass of your water before you put it inside the sun and measure the mass again after you remove it from the sun. The difference in mass is the quantity of water that is evaporated.
 There are different type of scale and the one that you use will depend on the size of the material that you want to measure.
