Below is the lab data for the lab where we separated iron filings, salt, and sand from a heterogeneous mixture. Each group of data is from a different period so make sure you get the right one!
You'll need to compare your data with the classes in terms of precision and compare your data with the actual data that I will give you here:
Iron: 9.2%
Salt: 15.6%
Sand: 75.2%
If you missed the lab, the YouTube video below gives a quick overview of what was done in class. The only difference is that we did not evaporate the water but rather let the sand dry to get the mass of the sand to calculate the mass of the salt. If you need data, please ask a lab partner for data. Thanks!
