Question

What tool(s) would you need to use if you are going to make the measurements necessary to calculate the density of a rock? (2 points)


balance

scale and crucible

graduated cylinder and balance

crucible and graduated cylinde

Answer 1

I'm thinking B. Im pretty sure you use a scale, but I'm unsure about the crucible part.

Answer 2

I'm thinking B too.. Confused about crudicle..

Answer 3

i would go with b

Answer 4

Ok thanks both.

Answer 5

Please fan @mikey he can help amazingly!

Answer 6

Density = mass / volume
Think of what you need to measure mass and volume

Answer 7

fan @brooke..help00 as well she knows more than me

Answer 8

Fanned you both! :)

Answer 9

:)

Answer 10

:)

Answer 11

What about "C" graduated cylinder and balance?

Answer 12

Wolf- you use graduated cylinder for volume and balance for mass. Would that be the answer?

Answer 13

I'd say I think it is "C"

Answer 14

tell us whos wrong @ryleepaisley10

Answer 15

This is hard....

Answer 16

If you choose "B" - a crucible does NOT measure volume.

Answer 17

I do believe I'll go with C just because it does make more sense.

Answer 18

"graduated cylinder" to determine the volume
"balance" to measure the mass

then
\[density=\frac{ mass }{ volume }\]Done!

Answer 19

Okay 3mar, now we have 2 that choose "C"

Answer 20

Thanks all!

Answer 21
