I’m sorry no one helped you with those questions. But could you please be a doll and give me the answer for the multiple-choice questions 1-15. Pleaseee I’m so desperate.?
FALSE You are never allowed to stand on the top of the ladder even if all legs are on the ground
Dissolves easily in water
We can get the vapor pressure of the solution from this formula:
Pv(solu) = n P°v
when n is the mole fraction of toluene so we can get by substitution in this formula:
n = moles of toluene / (moles of cholesterol + moles of toluene)
= 5.4 / ( 0.99 + 5.4) = 0.85
so by substitution in vapor pressure formula:
∴ Pv(solu) = 0.85 *41 = 34.85 atm
