These tools should be used to record the most complete data about a gas.

a.) a gas-collecting bottle and an electronic balance
b.) a graduated cylinder and a thermometer
c.) a manometer and a thermometer
d.) a syringe and a manometer

I think the correct answer from the choices listed above is option C. The tools that should be used to record the most complete data about a gas are a manometer and a thermometer. Pressure and temperature are important measurements for a gas since from these data we can calculate any other properties of the gas.

The best and most correct answer among the choices provided by your question is the third choice or letter C. Manometer and thermometer are tools that should be used to record the most complete data about a gas.
A manometer is an instrument for measuring the pressure of a fluid, consisting of a tube filled with a liquid while a thermometer is a device that measures temperature or a temperature gradient.
