Sodium Chloride Lab (Brian)

Problem: What is the maximum amount of table salt that can be dissoloved in 200mL of water?

Observations:

   
Trial
Volume of Water (mL)
Mass of Salt (g)
1
10
1.01g
2
20
2.14g
3
40
4.02

Analysis:
    1. the units for the slope of our graph was g/mL
    2. the slope repersents how many g of salt in a certain amout of ml of water
    3. our best fit line prediction was 20.1 g

   


              

20.1 - 70.8 = -252

     20.1
