ok.. can you help with another easy one?

Answer 6

Does that make sense?

Sure

Answer 8

Answer 9

Well you need the mass and the volume

Answer 10

What do you think you do next

Answer 11

I dont know, divide?

Answer 12

Yes an easy way to remember density is \[\frac{ M }{ V } \] which kind of looks like a heart if you write it out

Answer 13

lol okay.

Answer 14

Is that it?

yep, thanks!!

Answer 16
