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) \(0.92 * 100 = 92\) <Solve using the formula which is:
Mass=Density×Volume
\(M=D*V\)

2) \(3.98 ml\)

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

\(5*2*4=40\)
\(\frac{300}{40} =7.5\) (Answer=7.5)
