Question

How would you find the density of a gallon of milk?

A.Find the mass of the gallon of milk and then divide by the number of cubic centimeters in a gallon
B.Find the mass of the gallon of milk and then multiply by the number of cubic centimeters in a gallon
C.Convert a gallon into cubic centimeters and then divide by the mass of the gallon of milk
D.Convert a gallon into cubic centimeters and then subtract the mass of the gallon of milk

Answer 1

Density is mass (sometimes weight) per volume. To get those units, we multiply by the mass, and divide by the volume. Which answer does that?

Answer 2

either A OR B ?!

Answer 3

Which one?

Answer 4

C also sounds like it could be it

Answer 5

Nope. Check what I wrote above, and read the possible answers carefully.

Answer 6

how could it be if it includes subtracting @AnimalAin

Answer 7

Which answer has us dividing by the volume?

Answer 8

Density = mass divided by volume.

Hint: volume will be measured in cubic metres, or centimetres, etc.

Answer 9

it souns like its C!

Answer 10

*sounds

Answer 11

Not C. C gives the reciprocal of the density. If you work it that way, you get volume per mass. That is backwards.

Answer 12

C.Convert a gallon into cubic centimeters and then divide by the mass of the gallon of milk

This tells you to divide volume by mass, which is not correct.

Answer 13

Its A b/c its saying find the mass & then divide

Answer 14

Correct. Find mass, divide by volume.

Answer 15

Correct. Do math every day.
