Question

step 2: measure the reaction rate at ~20 - c (room temperature)
your tablet dissolved at 38:60. the average time is 34:20. divide the mass of the tablet (mg) by the volume of water (l) and then divide that by the average time to compute the reaction rate. use significant figures. record in the last column of table a.
temperature of the water: °c. reaction time: seconds done

Explanation:

Step1: Identify given values

The volume of water is $250\ mL = 0.25\ L$, and the average reaction - time is $34.20\ s$. But we are not given the mass of the tablet, so we can't fully calculate the reaction rate as described in the text. However, we can record the given values for the blanks. The temperature of the water is given as approximately $20^{\circ}C$ in the step - 2 instruction and the reaction time is $34.20\ s$.

Answer:

Temperature of the water: $20$ °C. Reaction time: $34.20$ seconds
