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!

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 
1) [tex]0.92 * 100 = 92[/tex] <Solve using the formula which is:
Mass=Density×Volume
[tex]M=D*V[/tex]

2) [tex]3.98 ml[/tex]

3) [tex]V=L*W*H[/tex] (Length  × Width × Height)

[tex]5*2*4=40[/tex]
[tex] \frac{300}{40} =7.5[/tex] (Answer=7.5)
