Our First Lab :0

In our first lab, we conducted an experiment to see how much salt can be dissolved in various amounts of water then make a conclusion on how much salt could be dissolved in 200mL of water, using a graph. In this graph made a line of best fit and scrolled to 200mL and from there we took our estimate which was around 38.??g of salt, but our answer was not even close. The real answer was around 70.??g of salt. Though not so dangerous, in this lab we followed procedure and wore all safety gear and followed safety precautions. In this lab it is also important to ask what temperature of water to use because your results will reflect on how much salt can be dissolved in water.

                                        
The graph sort of looked like this but this is just an example:
