Question

I need help with the following question, I am confused!
A block of material has a volume of 2 m3. It has a mass of 1 × 10^4 kg. Calculate the density of the material sample and express your results in g/cm3 with appropriate scientific notation.

Answer 1

Do you know what density is?

Answer 2

No I don't!

Answer 3

That is all that I was given.

Answer 4

Density, as the name suggests, is how dense a thing is. Imagine a basket of oranges. There are 5 oranges in this basket. The basket is 30cm^3 large. The density of the bakery would be 5 oranges per 30cm^3.

Answer 5

So density is the amount of things in a specified volume. Mathematically, density mass over volume.

Answer 6

Ok, so how would I calculate the density with a mass of 1 × 10^4 kg, and a volume of 2 m3?

Answer 7

I don't get how the 2 m3 could be divided by 1 x 10^4 kg

Answer 8

Actually, its the other way around. Divide the mass by the volume

Answer 9

So the density is 5000000 g/cm^3?

Answer 10

Nearly there. Did you convert metres cubed into cm cubed?

Answer 11

Actually, its the other way around. Divide the mass by the volume

Answer 12

Yes I did

Answer 13

10^4 kg = 10000kg = 10000000 g

2m^3 = 2000000cm^3

Answer 14

Did you do those conversions correctly?

Answer 15

I believe I did, I got 5000000 g/cm^3. Could you confirm if this is true?

Answer 16

10000000/2000000=5

Answer 17

So 5g/cm^3 is the correct answer?
I got 5000000g/cm^3.
Do you know what I could have done wrong?

Answer 18

How did you get 5000000g/cm3 in the first place?

Answer 19

Could you show me your work so I can see what I did wrong?

Answer 20

Oh I think I know

Answer 21

Does that look good now?

Answer 22

yea

Answer 23

Thank you for being patient and helping!

Answer 24

No problem. :)
