Measuring

The graduated cylinder has graduations on it that will enable you to read the exact volume of gas that was collected. Before recording the volume of gas collected, make sure that the level of water in the graduated cylinder and the level of water in the basin are even with each other.

Record the volume of gas collected in your laboratory notebook by carefully reading the graduated cylinder.

Thoroughly wipe the lighter clean and dry using a paper towel and weigh it on the balance. Again, record the mass to the nearest hundredth of a gram.

Measure and record the temperature of the water bath using the thermometer in your laboratory drawer.

Record the barometric pressure. The value of the barometric pressure will be provided by the TA.
