Stoichiometry Of Water Lab Report
Get all the equipment’s ready and put them on a table.
Take a pair of goggles and put them on and make sure hair is tied up, if long, using any sort of hair band.
Take the 100ml glass beaker and place it under the water tap’s opening, the place where the water comes out from, then turn the tap on. Do not turn the tap off until the water inside the beaker reaches the 50ml mark, to ensure that there is only 50ml of water in the 100ml beaker.
Then take the beaker and place it somewhere safe on the table.
After that take the scale and plug it’s wire in the socket, then turn the switch next to the socket on.
Then turn the switch on the scale on, which is located on either the sides or the bottom of the scale.
After that take the plastic boat and place it on the scale.

click on the button that says “zero” on the scale, to ensure that the scale doesn’t measure the size of the plastic boat.
After that take the packet of brown sugar, then carefully using a teaspoon, place a few spoons of sugar on the boat. Continue this until the scale shows that there is 25g(the measurement doesn’t have to be exact, however should be as close as possible) of sugar on the plastic boat. If it exceeds 25g, then take some sugar out and place it back on the packet.
Take the stopwatch , make sure it is set up so that it measures time in seconds and hold it with one hand.
Using the other hand, take the plastic boat and carefully pour the 25g of sugar into the 100ml glass beaker, and start the stopwatch immediately after pouring the sugar in.
Take the stirring rod and stir the water and sugar twice every 10 seconds, so when the stopwatch shows the multiples of 10. e.g. 10, 20, 30, etc.
Continue step 12 until all sugar has dissolved. All sugar has dissolved when there are no particles flowing around in the water.
Pause the stopwatch when all sugar has dissolved and record the data on a computer or notebook.
Take the solution found in the 100ml beaker, then pour the solution into the sink.
Rinse the 100ml beaker using tap water, then dry it during a towel.
Each gram of sugar has to be experimented 3 times, to be able to plot the data collected for the three trials performed for the different masses of sugar, on a graph. Therefore, repeat steps 3-16 twice.
Four different masses of sugar(30g, 35g, 40g, and 45g) have to be experimented in this experiment, therefore repeat steps 3-17 three more times, however with sugar with masses of 30g, 35g, 40g, and 45g each
time.
