Answer:
Explanation:
Partial pressure of oil = mole fraction of oil x total pressure
mole fraction of oil = mole of oil / mole of water + mole of oil
= mole of oil = mass of oil / molecular weight of oil
= 20 / 100 = .2
mole of water = 80 / 18
= 4.444
mole fraction of oil = .2 / .2 + 4.444
= .2 / 4.644
Partial pressure of oil = mole fraction of oil x total pressure
= (.2 / 4.644 ) x 760 mm
= 32.73 mm Hg .
Carbon atom with iron and helium
The brain. The brain tells the body what to do same way the nucleus does for the cell.
I think the best answer from the choices listed above is option C. With this accident, both should be alert and do what should be done. <span> Lee should tell the teacher while Celia washes her arm with soap and water.
