To measure mass accurately in the lab__________ is used

• Grams

• a scale

• a triple beam balance

• a graduated cylinder

The _______ show the mass of the object

• riders

• numbers

• beams

• adjustment knob

the scale of the beam in the front is from

• 0g - 10 g

• 0g - 100g

• 0g - 500g

• 10g - 100g

the scale of the beam in the middle is from

• 0g - 10g

• 10g - 500g

• 0g - 100g

• 0g - 500g

How do find the mass of a liquid?

• pour the liquid on the balance and measure accordingly

• pour the liquid into a container and place both on the balance to find the mass

• measure the mass of an empty container them pour the liquid and measure both; finally subtract the mass of the empty container

• place an empty container on the balance and slowly pour the liquid until you find the correct mass

why do you have to "zero" a balance before using it?

• to make sure all the measurements are accurate

• a balance doesn't have to be zeroed

• the balance comes with zero from the factory

• you zero a balance after the weight has been placed on it
