An electronic scale is used to measure the mass of an object. The instructor will demonstrate its use.
- Obtain a small object such as dice. Record the mass of the object in grams (g) and milligrams (mg).
- Tare the weigh boat. Empty the salt into the weigh boat. Record the mass of the salt in grams (g) and milligrams (mg).
You should consume less than 3 grams of salt/day. You weighed an amount that many in the United States consume daily. How does this compare with the recommended amount?
