amount of matter in an object
Matter-is anything in the universe that has mass and takes space Triple Beam Balance-measures the mass of an object
Finding Mass Directly
1. Zero out the triple beam balance.
2. Place the object on the pan of the triple beam balance scale. 3. Move the riders (starting with the 100g and ending with the 1g)(move one at a time-make sure) until the balance pointer rests at zero.
4. Add the measurements on all the riders and record the quantity in g.
Finding Mass By Difference
1. Zero out the triple beam balance.
2. Find the mass of the empty container.
3. Find the mass of the container with the liquid.
4. Subtract the container’s mass from the total mass to get the mass of the liquid.
5. Record the measurement in g.
Measuring Out a Substance-powders
1. Zero out the triple beam balance
2. Find the mass of the weighing paper.
3. Add the mass of the weighing paper to the desired amount of the substance..
4. Preset the riders to this amount.
D=M/V
5. The balance pointer will drop below zero.
6. Slowly add the substance to the weighing paper until the balance pointer is straight at zero.
7. Record the measurement in g.
Volume
the amount of space an object takes up
Meniscus- the curved surface of a liquid
Graduated Cylinder-used to accurately measure the volume of a liquid
Overflow Can-used to find the volume of large, irregularly shaped solid objects through water displacement
1mL=1cm3
It’s easier to see the meniscus in a graduated
