question
What are the 3 Mass Methods?
1. Measuring Mass Directly 2. Finding Mass by Difference 3. Measuring Out a Substance
question
Measuring Mass Directly
Used to find the mass of an object. Step 1 - Place the object on the pan. Step 2 - Zero out the TBB. Step3 - The mass is determined by the positions of the riders. Record the mass.
question
Finding Mass by Difference
Used to find the mass of a liquid in a container. Step 1 - Measure the mass of the beaker(a). Step 2 - Pour in your liquid. Step 3 - Measure the combined mass(b) of the beaker and the liquid. Step 4 - Subtract the mass of the beaker(a) from the combined mass(b). Therefore, b - a = Mass of Liquid
question
Measuring Out a Substance
Used to obtain a specific amount of a substance. Step 1 - Find the mass of a paper plate. Record mass. Step 2 - Add the mass of the paper plate to the desired mass of the substance. Step 3 - Preset the riders to the amount (the sum) in Step 2. Step 4 - The substance is then placed on the paper plate a little at a time until the zero pointer is balanced with the zero point.
