Answer:
29.256 torr.
Explanation:
Number of moles
Glycerin:
Molecular weight of glycerin = (12*3) + (1*8) + (16*3)
= 36 + 8 + 48
= 92 g/mol
Number of moles = mass/molar mass
= 25.2/92
= 0.274 mol
Water:
Converting g/ml to g/l,
1000 ml = 1 l
= 1 g/ml * 1000 ml/1l
= 1000 g/l
Mass = (density * volume)
= 1000*0.124
= 124 g.
Molar mass of water = (1*2) + 16
= 18 g/mol
Number of moles = mass /molar mass
= 126/18
= 6.89 mol
P°solution = xsolvent * P°solvent
Where,
xwater = xsolvent = mole fraction of water.
Mole fraction is defined as the number of moles of a component of a solution divided by the total number of moles present in that solution.
xwater = mole of water/total mole of solution
Total mole = 6.89 + 0.274
= 7.164 moles
xwater = 6.89/7.164
= 0.962
P°solution = xsolvent * P°solvent
P°solution = 31.8 * 0.962
= 29.256 torr
Answer:
When secondary bile salts (or acids) lack a OH, they are reabsorbed
Explanation:
The lost of a hydroxyl group (OH) in the bile salts structure means less hydro solubility. Thus, they are not eliminated, conversely, the are reabsorbed for intestine and they go back to the liver.
I hope my answer helps
Answer:
Yes, it will.
Explanation:
The friction of the surface will tug at the book and lower it's velocity, causing it to slow down.
