Question

Someone please help! It is a few science questions. Fairly easy!

What is the mass of 100 ml of corn oil?

What is the volume of 35g of copper?

A rectangular solid is of unknown density is 5 metes long, 2 metes high and 4 meters wide. The mass of this solid is 300 grams. Given this information for this homogeneous (alike through) material, calculator its density.

I know that Density=mass/volume but i don't know the volume for that one ^

Please answer fast!

Answer 1

so for the first one the answer is : 0.92 * 100 = 92
the second one the answer is 8.80 :)
and for the third one the density is 7.5
i hope this is helpful
have a nice day

Answer 2

1)
`0.92 * 100 = 92` <Solve using the formula which is:
Mass=Density×Volume

`M=D*V`

2)
`3.98 ml`

3)
`V=L*W*H` (Length × Width × Height)


`5*2*4=40`

`(300)/(40) =7.5` (Answer=7.5)
