Question

Answer 1

\[\frac{ kg }{ 1 }\frac{ m ^{3} }{ kg }= \text{ volume of oil} \]

then divide by the area to get approximate diameter of molecule.

it's all in the units.

Answer 2

huh?

Answer 3

don't you just multiply the radius by 2?

Answer 4

you convert the mass of the oil into a volume via the density. from there you divide the volume by the area to get a linear measure which is the thickness of the the slick, approximately the diameter of the oil molecule.

Answer 5

can you show me with step by step using formulas. I am having toruble following you

Answer 6

how do we get the area?

Answer 7

start with the mass and convert to volume withthe density...

\[\frac{ 9\times 10^{-7} kg}{ 1 }\times \frac{ m ^{3} }{ 918 kg } = 9.80 \times 10^{-10} m ^{3}\]

Answer 8

thta's the volume.

Answer 9

so hwo do we find the area and get ot the diameter?
